There's only 2 shore dives in SE Florida that might be worth a tank fill and that's Lauderdale by the Sea (LBS) ust off Fort Lauderdale and Blue Heron Bridge in West Palm.
Having dived both I can tell you that LBS is hardly worth the long swimout which can take a 1/2 hr or more, sometimes battling current that can sweep a diver far along the coat requiring a long walk back the beach with gear, plus waves, lots of boat traffic, and requiring a diver to tow a flag. It's completely unnecessary to do all that when that reef is regularly visited by local dive boats. The reef itself is lackluster, but probably beats a great day at work.
Blue Heron Bridge can be more interesting, the entry is off the beach and is usually done only at high slack due to low visibility and current other times, but locals have told me they sometimes get a good dive in at times other than high slack.
I've never dove LBS, but I can't imagine 100yds to be a 1/2hr swim?
I think whenever I talk to Floridians about viz I have to keep things in perspective. A day of bad viz in FL is an amazing day of viz compared to home. I heard a guy going on and on about bad viz @ BHB..... only to find out his idea of bad is 15'
I'm sure some days are a wash at BHB, and I'm sure the current gets rough at LBS.
