Request suggestions for LAC matches -- also, chance me for Williams and Swarthmore!

While WIlliams and Swarthmore are excellent choices for math reaches, my first thought as to the best LAC for math would be Harvey Mudd. You should also look at Carleton - their math department is excellent.

If you are interested in attending a women’s only college, Brin Mawr has an excellent math program as well, and it probably a match/high match for you.
