Im also in broward and acerola/barbados cherry are fantastic, the ripe fruit tastes like sweet tarts to me. Allegedly they used to plant them around schools down here and the kids would forage for them and get a boost in vitamin c, but then we learned how to synthesize it and the practice of planting them declined, but it is still time tested kid approved. The only problem ive had is with wind damaging the leaves during windy season. I havent experimented with it but their growth habit seems like it would respond well to hedging, they also have exceedingly dense wood, very sturdy when established, and you can get one at lowes, very available here.
I know its not forageable, but if you have the space for something extra I think pineapples look so beautiful and bring so much texture to tropical landscaping. Im growing some sugarloaf pineapples now and they are totally spineless/kid friendly
