Thirding. Most of the areas off the main drag feel suburban but there are all kinds of amenities within walking distance. Tons of young families. The farmer’s market is awesome. Check out Hamilton-Lauraville Mainstreet.Hampden might fit your criteria but definitely has more of the issues that come with “city life”.

Eta: maybe check out Medfield? Walking distance to Hampden, close to multiple grocery stores, but a little more residential and quiet.
