Bahamas here, waterfront as well. Vines - Chalice vine, Solandra guttata, is beautiful, fragrant, and tolerant of salt spray. I’d say that’s a front runner. Bridal bouquet, Stephanotis floribunda, is another. Native beach vines such as railroad vine, Ipomea pes-caprae, and beach pea, Canavalia maritima, are two pink/purple flowered possibilities for full beach exposure. Both can be trained up a trellis or similar structure. Clock vine, Thunbergia grandiflora, are durable and bring a scarce lavender blue colour to the mix. Fruiting trees for beachfront: Tamarind will survive anything and still bear, and Indian almond, although this one can become invasive. Native cocoplum will thrive, too, tough as nails and low maintenance with fruit that make great preserves. Seagrape of course, and back from the beach, papayas bear within weeks all the year round. Dwarf cavendish or other low statured bananas will get shredded less by sea winds. Short statured coconuts like “Maypan” bear close to the ground, don’t get too tall, and are immune to lethal yellowing disease. Other options include agaves (use your native ones! Birds love the blooms), your native lignum vitae trees for a blue flowered tree stunning in flower and fruit that can survive searing drought and seawater inundation, buttonwood, seven year apple, Plumeria (native or non), many hardy bromeliads, Caribbean native tree cacti in the Consolea group, your lovely native thatch aka tier palm Coccothrinax alta, and so many more. As for expanding your palm plantings, also consider Veitchia, Pritchardia, Latania, Pseudophoenix and the show stopping Bismarckia is surprisingly tolerant of drought, salt, and hurricane winds. Hope this helps, I’ve been at this a long time and wasted a lot of money to get to where I am. More on reddit.com
