Bonaire is all small stuff - there's one chance to see sharks with the specialized east coast divers. You will see turtles, tarpon and rays there though. Tarpon will feed in your light on night dives. Some barracuda also. Interesting small stuff, seahorses, scorpionfish, slipper lobsters etc.

Sharks and wrecks are the Bahamas. Nassau has shark feed dives with Stuart Coves and over a dozen wrecks - a few natural, a few put down and a few movie sets. They filmed sequences for two Bond films - Never say Never and Thunderball there. Also Into the Deep was mostly filmed there - so there's some diveable movie sets. Sometimes at wrecks near the feed site you'll find sharks waiting around for it. Check their map ane hover on each site flag for details. Coves is $125 for two tanks/$195 for 4 (all day)
Stuart Cove
Bahama Divers is the other option there. All boat dives and not the cheapest either - 2 tanks runs around $120-140. They do a 2 tank wreck/reef dive and dive 4 different wrecks. Also the Lost Blue Hole is one of their signature dives.

Move over to Freeport (Grand Bahama) and you've got UNEXSO - they do shark dives, dolphin dives and wreck dives. They put down a wreck about a decade ago and there's also the Theo. It can be more advanced, it's deep (100') and huge.

I also recommend Fred Riger at Grand Bahama Scuba also. He's been there about 3 decades. And does dives at all depths.

No shore diving anywhere on either island. I don't know the Out Islands well enough to comment but we did see a whole lot of sharks off Bimini once as we passed thru there on a liveaboard.
In a week on Utila we saw probably a dozen reef sharks all told. Most at the northern dive sites which most operators will go to - almost all the accommodations/rentals etc. are on the south side. The Halliburton is their deep wreck and there's at least one more IIRC. There's some prettty vertical walls off Utila's north side and good diving in the south also.
One of the better dives we did there was Black Hills - a seamount that rises to 40'. One morning dive we saw all this there: About 100 Barracuda eyeing the schools of anxious grunts, 6-7 3-4' Oceanic Triggers, an equal number of 2-3' Grouper. Several turtles and lots of smaller reef fish. As we were leaving two reef sharks were making their way up from deeper water.
I've also seen 3 of the more interesting things there - seahorses at one site that was nothing more than an angled sand flat with some weed on it, not what I'd call seahorse terrain but they were there, an electric or torpedo ray - no one touched it to find out which and a Ruby Red Lipped Batfish - the only one I've seen in the Caribbean. And if you go in spring or possibly September (IDK why) there's a better than decent chance to snorkel with Whale Sharks - we did with 8 of them. Talk about an awesome remembrance - one was longer than our boat.
Turks/Caicos is where I went for pelagic diving - it didn't disappoint. If you stay on Provo you have access to two different options. One is the Grace Bay and Northwest Point area just off the island a few minutes by boat. (no shore diving there) Often there's grouper, we saw maybe 2-3 sharks over 2 days of diving and they were mostly leaving as they saw us. If JoJo the dolphin is still alive, he hangs out there. There really are no divable wrecks in Turks/Caicos.
https://www.visittci.com/other-things/wreck-diving however an interesting shallow dive there is Thunderdome. The story we were told is that it's a failed adventure show set.
The other, IMO better diving is south off West Caicos and French Cay. Both uninhabited so dayboats from Provo do go out there. It's a proces though - they'll pick you up in a van in the morning along with other divers from the resorts - most of which are on the north shore near Grace Bay - take you to a south side marina and their boat. 45mins or so later you're at the first dive site - they do two dives with lunch. Then reverse the process - you won't be back at your resort till 2-2:30 PM. Add a third dive like Caicos Adventures does and it's 4:30. Not exactly cheap dives either - mid $100+ since you pay for the ride, gas and lunch.
It is however among the best wall diving I've ever done. Sharks at French Cay will completely ignore you and go about their business. There are so many stingrays you'll stop counting them. Usually some cuda also. And basketball sized lionfish. Hanging out in the blue water over the wall is an experience by itself - it's almost eerie. We dove off one pinnacle, the DM said the next flat spot is about 1000' down.
Provo is very nice but it's also very expensive. Grace Bay Beach is one of the finest in the world - that costs extra...lol. Ports of Call is an affodable option - it adjoins a small mall and there's several restaurants nearby. Also one or two small casinos and some upscale beach bars.
I don't know Coz.
