Nano Fish List

Rams are adorable, charismatic, and charming by definition - and will absolutely pick your shrimp to ribbons. Don't do it, man... I made this mistake.

On another note, chocolate gouramis look great in a naturalistic, slightly darker tank. They're like leaves in the water. I'm going to pretend you opened the floor to a vote, and vote them as your gourami of choice.
 
You might look in to harlequins for the rasbora department. I have a few, and they look very nice when the light catches them.

Take a look at checkerboard cichlids, crenicara filamentosa (or whatever the taxonomists are calling them these days).

Well then...

+1 Chocolate Gourami

As a side note, I went to one of the LFS's in town and they had a surprising amount of the fish listed here! I didn't expect to see a sparrow rasbora or a clown killi. And it was awesome to see a live scarlet badis. I love that fish even more now.They also had Emerald Blue Rasbora's listed as red stripes.
 
There's no way I'd put swordtails (at 4-6 inches!), dwarf gouramis, "dwarf neon blue" (m. praecox: to 3") or rams (any of these in any color forms) in a "nano fish list". But many on your list are interesting!! My only "nano" tanks" have been much smaller volume & surface area, 20g long at most, with a few in a 4ft 40g.

Being a loach lover, I have to add Vietnamese multi-striped (yannanalis cruciatus) loaches & rosy loaches (whatever they're called these days, lol), both shrimp safe IME, as are dwarf corys & apistodoras. Kuhli loaches, while they can grow to 3 or 4 inches depending on species, are also very mellow & tiny fish-safe, & all but maybe newly hatched-shrimp safe, not a bad size for your tank.

So many nice options! I'd skip all livebearers, they tend to overpopulate without a fish to eat fry or a ready market for them, something else to consider...
 
Espei Rasbora's are nice, Endlers are nice, Ember Tetras are nice
