Casa Mugrienta is spot on about some of the shortcomings of Miami. At 56 you might not give a f--k but I'm with him on the vapid superficiality. West LA might as well be Wisconsin with how roots and down to Earth it is in comparison.
The vast majority of April-October you will be driving 1.5 hours to get dropped in on and murdered by sea lice/man-o-war (Juno Pier) or 3 hours to get dropped in on (Fort Pierce Inlet) or 3.5 hours to catch 30 closeouts and not see a makeable wave for weeks at a time (South Brevard) or 4 hours to surf soft longboard waves (Satellite Beach) or 5 hours to get dropped in on by all of Daytona, most of Orlando, and far more of Tampa than you expected (Ponce/Smyrna).
If you don't mind golf/tennis in the swelter, or you like fishing/snorkeling, that changes things dramatically.
I think El Salvador is the best choice for frequent flier miles. Works in Florida's off season, 2-ish hour flight, 30-45 minutes from airport to lineup. Winter will open up interesting options like the Bahamas, Puerto Rico, DR, VI, Barbados....
If you don't like hot/humid weather, or you have a serious problem with insects, I'd avoid it.
South Florida's Bahamas blocking IMHO is mostly analogous to lower Santa Barbara County. Specific winter angles and rando windswells are it.
I think I have 5 years more to give to something but moving to Florida scares me as much a Pascuales at 8-10 foot.
A word on being 56. Personally, I think there is slightly more time to get to your feet at Pascuales than the average wave between Spanish House and South Beach. There aren't that many El Porto-style closeouts where you can take off at a leisurely pace and pump twice, where, if the South Bay LOLs at the thought of you making the wave, it at least lets you in on your own terms.
South Brevard/Indian River/Central Palm Beach Counties, no such luck. You one-motion the pop-up/pump/tube tuck/bail, or you're getting lipped and bounced.
The exceptions to this are unbelievably crowded and/or surprisingly localized.
On the plus side if you can get down, into, and out of the average left at B-grade Central PB, every racey left on Earth that's named Impossibles you will be renaming "Literally all fucking day; this is the slowest and most workable wave I've surfed since my last trip here-ables".
