Best Caribbean island for 3 women in their mid 30’s

Hello we are 3 women in our 30’s looking for a tropical destination within a 3-5 hour flight from NYC during June.

Looking for beautiful beaches, good food, and some night life (nothing crazy but we would like the option to go to a bar/cocktail lounge/beach club post dinner). As we are not into group tours, we also want somewhere that is safe enough for us to wander and explore on our own (not planning to be wandering alone late night, but you get the idea).

Budget is not an issue, lodging we really want adults only, or at least a spot not geared towards families/has designated adults only areas.

Places we are considering, but open to others: Saint Lucia, Saint Barts, Saint Martin, Grenada, Turks and Caicos

I have been to Aruba, Jamaica, The Bahamas, and Belize multiple times so no on those spots.

Any help would be amazing as there are so many options, hard to narrow it down.
