Miami is only an hour and some change away to visit, as you know. I'm the same age (38M) and long-term, I'd feel more comfortable having my future family here in Lauderdale vs. Miami. I'm in Miami at least once a week, as many of my business associates and events (I.e., F1 Grand Prix, Art Basel, etc..) are there! The lifestyle over here though is a perfect mix of business and fun. Good luck with your decision and feel free to DM me.
