I am also looking for an OOT community for my family, although we are probably older than you (since you titled it “young community”. We’re in mid 30’s.
I think Cleveland, Detroit, Phoenix all offer nice frum communities for a mainstream “learning/working” family with the amenities you’re seeking. There are others but they may be too “Kiruvey”(very high concentration of balei teshiva) etc, I don’t know if that bothers you though.
