I’d check out Hopkinton. It seems to check most of your boxes. Schools are very good, crime is pretty much unheard of, and the people are fantastic. I’m not a fan of Concord really but if you’re looking for stuff to do and medical facilities it’s fine and right nearby. Hopkinton is also fairly centrally located and right on 89 so easy access to a lot that NH has to offer as well as Dartmouth-Hitchcock in several locations.
