Middlebury’s language offerings are very good, especially for a liberal arts college, but the style of instruction isn’t any different from that of any other top college. Where Middlebury really shines is its summer school for languages – which offers a much more intensive style of instruction and hires many non-Midd professors.
Also note that Midd’s offerings are very slim, about a dozen languages. That’s plenty for the OP, whose languages of interest are commonly offered, but it wouldn’t satisfy everyone. Unlike the Ivies or (especially) large public universities like Berkeley or Indiana U, Middlebury doesn’t offer Celtic languages, African languages, southeast Asian languages…etc.
I recommend focusing on strong Arabic programs. You have a fair amount of French under your belt, and most good colleges have adequate French offerings. Latin is more rarely offered, as merc81 pointed out, but it’s not uncommon to arrange for an independent study (or group independent study) for advanced Latin reading if there’s some classics professors on campus. (Not ideal for a classics major, but I don’t get the impression that’s your goal.)
Arabic is a very different beast – difficult to pick up and requires lots of practice in reading, writing, and speaking to get down. You should also plan to spend some time abroad (e.g. through the Critical Language Scholarship) to improve your ability.
There’s quite a bit of interest in Maghrib studies these days – possibly a way of combining your interests in French and Arabic. There’s even some very interesting Phoenician and Roman ruins there.

I second Mom2aphysicsgeek’s recommendation of the Language Flagship programs.
You have great stats. Check out Michigan, Chicago, Cornell, Emory, Dartmouth, Tufts, Georgetown, GWU, and Wash U in particular, though transfer admissions is definitely tough at some of these. I second most of merc81’s suggestions in post #1 and would add Swarthmore to the list of liberal arts colleges.
If cost isn’t a problem, you could add NYU and some out-of-state publics (U Washington and UT Austin in particular).
