Not an interior designer here, but I have completely remodeled (ripping apart down to the studs) 3 kitchens in my life. I love the cherry cabinet/green counter combination, which I agree would be stunning. I've always used cherry wood for the cabinets, and they age well and are timeless; they will darken with age, however. I agree that the white floor doesn't sound like it would mesh well at all. The other problem is that you might get this sense of floating with a white floor. A dark floor really does give you a grounding (so to speak). I also wouldn't want a white floor in a kitchen-- too much daily cleaning. Since you're using natural materials for the cabinets and the countertops, I would use a natural material for the floor-- either wood, or another natural material that would go well with your other choices. I agree that this would be warmer, too. Hope that helps, though I'm not an interior designer.
Edit: Sorry, I just re-read your post and saw that you do have a tiled floor and it does have some beige in it. I don't know. Can you re-do the cabinets and countertops before doing the floor? Then if it doesn't look good, you can change the floor as the last part of the renovation?
