I agree with Mike above. The only fish that I think would be impossible to jump are Seahorses.
Other fish that are highly likely to jump are Blennies, Firefish, Jawfish, Anthias and Dottybacks. I've found Wrasses, Blennies and Firefish most likely to jump at any random time--these should be absolutely avoided in an open tank.
Gobies, Jawfish, Anthias and Dottybacks tend to jump when first introduced, but are less likely to once settled--try these at your own risk.
Some fish that have a medium chance of jumping are Clowns, Basslets, Tangs and Angels. Fairly safe, but again, they may jump at some random time.
Safe choices would be fish that are slow methodical swimmers, such as Puffers, Filefish and Banggai/PJ Cardinals. It's not impossible for these fish to jump either, especially a hyper Puffer.
If I were in your position, I'd opt for a covered tank. Bulk Reef Supply has a decent 1/4" mesh DIY kit for a good price. Looks fine and doesn't reduce the lighting or hold in heat. Really opens up what kinds of fish you can keep without worrying about jumpers.
