Miami is a fair place to live, busy nightlife, lively during the colder months from snowbirds, etc. I'd say over 50% of Miami is hispanic, so naturally there are a large number of spanish speakers. The beaches are known to be nice, just depends what you are into. The traffic and driving shouldn't be terrible to adapt to, especially coming from NY.
If your job situation is better in FL, who cares about the little things? Good luck and enjoy
