Florida beach recommendations/intel

Greetings: I need some advice on the four legal clothing optional beaches in Florida. Which one should I bring my somewhat nervous wife to for her to get naked in public for the first time next month. She is 70 and in good shape but very apprehensive.

I have made solo trips to Haulover, Playalinda and Apollo beaches and love them all. Never been to Blind Creek but have heard great things about it.

Looking for a nice vibe and friendly people. Biggest downer/turnoff would be for her to encounter a creeper or witness some inappropriate behavior on the beach. Any and all input would be appreciated. Thanks in advance.
