Glad there are "or" in between each option and not "and", lol. I would stick with gobies and 1 swimming fish, like 2-3 neon gobies, a masked goby, and 1 swimming fish like the chalk bass or royal gramma. I thought Chalk bass had to be by themselves, didn't know you could "school" them, but I don't have much experience with them other than seeing them at the LFS. Chromis I think are a bad idea for that size tank, just my opinion. Jawfish.. ummm, major jumpers, so you would have to do something for a top on the tank to stop that.
I know your trying for a specific region for your fish so my ideas wouldn't fit your plan but this would be what I would put in a 10G, 2 Yasha Gobies, pistol shrimp, 2 neon gobies, maybe a watchman goby, and a pair of cardinals. Sounds like a lot but they are small fish. Again, I understand that isn't the direction you want to go.. just throwing out ideas.
