If you check out the Belladonna High School at Garden of Shadows, it might be something you like. The site is a bit moody right now, so you might have to try later.
http://www.digitalperversion.net/gardenofshadows/index.php?topic=9974.0It has a recess area, football (soccer) field, indoor basketball, and special classrooms such as science/biology, art, home economics and a few more. It has regular classrooms for young kids, older kids, and teens, plus room on the roof to build more floors.
I think it is community, but it's an easy switch with the residential cheat and the buyable mailbox/trashcan (go here:

Modthesims also has a bunch of schools:

Suburban houses are pretty much everywhere, so unless you have some spesific preferences, you could try out Modthesims. They've got several such houses.
