The only area that specifically leaps out at me as unique is St. Augustine, which is lovely.
St. Augustine is, arguably, the best city (albeit a very small one) in the entire state.
Agreed. It seems like the one really nice place in the state that's affordable to normal people (Palm Beach is great but you need a lot of money to live there).
It's getting pretty expensive here too, honestly. It's not at South Florida levels (yet), but it's getting there. If you're looking for a 3 bed/2 bath home here for rent, almost all decent ones are at least $1,500 per month and most are over $2,000. To buy they usually start around $250,000, but most are over $300,000 at this point. Considering the Jacksonville metro has chronically low wages, that's not cheap. I remember when this county was all woods, swamps, and farms, and most houses were quite old and everything cost at most half of what it does today.
