From Brooklyn to South Florida, Help!

After 20 years in NYC I'm moving from Brooklyn to Florida to be closer to family. They're split between Plantation/Davie/Delray and then farther up state in Sebastian. My criteria is an excellent school system that will support an IEP and I want to be within a 15 minute drive of a children's medical center of excellence like Nicklaus, Joe Dimaggio, Cleveland Clinic etc. (my son has mild cerebral palsy). I've been pretty set on Cooper City, but am starting to wonder if there are other areas I should consider, like Parkland, West Palm, Boca? What else should I be considering, please help!
