If your fake fruit looks real (not bejeweled or anything), you might see if there is a theatre group in your area who might want it for props.
Be a minimalist. There is no need to put stuff in any room unless you actively like it. That includes plants. And books. Of course, your spouse will have ideas on what to keep so you need to check before discarding (for us it is many of the books). I like the idea of emptying a room and only putting back things you currently want in it.
I don’t get “dated” as applied to one’s art and decorative objects collected over many years, presumably because they spoke to one in some way.
Also, call me crazy, but my bookshelves are full of books, not “stuff.” 
Although lack of sufficient book case space is a perpetual problem, and short of setting up stack in the attic I think I do need to cull the collection. There are things I definitely don’t want any more. Of course, there are piles waiting to take their place, LOL.
^^ my sister’s small houseboat has bookshelves, and they are charmingly crammed with books, small family pictures, homemade pottery from my dad. They are a treat to look at and to see what books she has. I love them. She has those really as her only decoration and it tells her life. For her the streamlined look wouldn’t work.
I think it can also be a misnomer to assume that you have to stuff bookshelves with only books! Books of course, but visually (and pleasing for someone like me) can be to break up rows or partial rows or stacks or piles of books with other items - like a bookend and then a little space! Or just SPACE.
It’s personal preference of course.
Oh, I don’t assume that bookcases HAVE to hold only books, it’s just that I have so many books. 
Actually, I do have a bookcase in the living room that displays collected objects, and only a few very old books.
Houzz dot com. TONS of beautiful photos of current decorating styles.
Take out everything except the big pieces of furniture. Box it up. Put the boxes away somewhere for awhile. Since the holidays are coming up, maybe clear out everything, decorate (if you do that) for the holidays, and then in January take a look at the boxes. Chances are, it’ll be clearer to you what you love and what is just stuff. Get rid of the “stuff”. Replace it with nothing for awhile.
What does one do if one LIKES the 1990s look? I like my fake greenery. I like my wire basket with fake fruit. I like my accessories. They make me happy. I get annoyed that the decorating gods have deemed something as outdated. Whatever happened to decorating to please oneself?
^^If you like it (and others who live there too) then keep it! OP indicated she wanted change and seemed to pinpoint fake fruit and plants as things to go.
For many making things fresh is motivating and satisfying. Just like new clothes, a new car, new hairstyle, etc.
I have coffee table books on my coffee table. A book of New Yorker Cartoons, some art books, a book of New York Times front pages - stuff like that.
I vote for putting the basket away for a while. My kitchen counters have stuff like crocks full of wooden spoons or whisks.
I have Napa Wine Cats and a freebie chichi house design (sent by some realtor) books on the coffee table in the living rooom. Periodically, my cats get tired of sofas and sit on the books.
I am turning into a minimalist when it comes to surface-based decor.The fewer pieces the better. Ditto wall art.
Speaking of wall art, I do have a place for one piece, just can’t find the right one. Mr. is deathly against having anything on the wall above our bed for safety reasons, but he agreed that a lightweight piece made from twigs or branches would be ok. Has anyone seen anything like that? I’d love some recommendations.
There’s nothing wrong with decorating to please oneself. I can wear a poodle skirt and saddle oxfords every day if I like, but let’s not pretend my dress wouldn’t be “dated.”
Personally, I think change is good from time to time. Wearing the same hairstyle for 4 decades, the same clothes, shoes, never thinking outside the box is within my rights, but to me, kind of boring. Not that you always have to be on the cutting edge and catering to every trend, but surely there’s a happy medium. But at the end of the day, no one “makes” you change.
BTW, I have no issues with decorating to please yourself. My kitchen walls are celery green because white and gray kitchens do not make me happy. I have a lot of stuff that I use out on the counters. I also have a little molding that runs around the top of the backsplash (I have hardly any upper cabinets) and I’ve got postcards, small art works, seed packets that I’ve stuck there. I also have small stuff on the window sills from our travels. A lucky cat from Japan, a Buddha from Thailand among other things. I’m not really of the less is more school of decorating though I admire it when other people do it!
Oh, to have counter space that could be devoted to decorative objects…
The “minimalist” look requires one to be very neat and tidy, no clutter allowed.
Lots of clutter stresses me out, but too minimalist feels cold and sterile to me. I admit I’m often in the “happy medium” camp in many areas. 
@conmama - it wasn’t really “decorative,” but I had a friend who had a large basket on a table that was filled with printed photos. All completely random. Old, new, baby, vacation, those fraternity and sorority pics, with friends, with family, black and whites of ancestors, etc. We had so much fun pulling out pics and asking/talking about them. We were in some of them ourselves!
But, I would probably just get rid of the basket.
@BunsenBurner - I would struggle with twigs or branches or a piece of driftwood, etc. One of my big things is ease of cleaning. That sounds difficult to dust/keep clean to me, so I woulnd’t like that.
Fewer items on surfaces or walls means less to dust/clean. A big win to me. But, I do understand not wanting to be too sterile. My kitchen counters were void of everything other than hand soap/paper towel holder, Keurig, and a fruit bowl. It just looked cold and sterile, so I added a small tray with a pitcher, napkin holder with the word, “gather” scripted on it, and little bird. I would much prefer to have a vignette like that than an appliance out. We are in a 935 sq ft condo, but I still keep all appliances tucked away. I did get rid of a LOT when we downsized.
I’m with others that say too much clutter stresses me out. I have read somewhere that all decorative items should be at least as large as a cantaloupe - ha ha! No little collectibles in groups - talk about lots of dusting! No thanks!
One more idea … since it is holiday time, why not put some large ornaments in the basket? Stick with one color scheme for a tranquil feel or several brightly colored ones for more pizzazz. After the holidays are over, you can try something different.
I have put my basket in my avatar. I hate getting rid of it, I think it’s pretty.
