If you really liked Smith, I would say that you probably would also like MHC. Aside from being in the same area and both being women’s college, I have heard that they have very similar vibes.
You should definitely visit before you choose, but based on what you’ve written, MHC seems the best fit.
I wouldn’t worry about grad school. MHC, Reed and Kenyon are all in the top of colleges which have the highest percent of students who do PhDs. Any would allow you to do a PhD, but what this tells you is that these colleges all have students with similar career aspirations and future plans as you do.
Like others, I don’t think that F&M sound like as good a fit as any of the other three.
Find out how you can meet with students at these colleges - there are often ways to connect to them online, and they should all have the possibility of coming to visit the colleges and, in some cases, staying overnight.
