I've also had great luck with tomatoes (just make sure they're determinate), peppers, and greens in containers.
I'm a member of a community garden that has an awesome co-op model (instead of everybody having their own plot) which is an amazing way to meet people and grow way more than I could on my own - so far this year we've had an abundance of greens, kohlrabi, kale, cucumbers, tomatoes, peppers, beans, carrots, peas, squash, and we even have some watermelons, potatoes, and pumpkins on the way! I don't think it's a model that exists too many places, but I love and recommend it - if you can get about 25-30 families involved it becomes pretty sustainable (we pay a $25 annual membership, all volunteer-led).
