If you like rasboras, "purple harlequins" (hinted to be a natural mutation that has been line bred) - after some reservation I got some from my lfs, colors can get very intense, deep blue/purple becomes almost black & can extend quite far "forward", gold/orange iridescence "patch" can extend from mouth to dorsal fin
Chocolate gouramis - get in a group of ~ 20, it's very interesting to watch their behavior (introduce whatever "dither" fish first as your tank is high light etc, also wait for plants to grow in somewhat), they hunt everywhere picking up the last bits of food (I feed frozen)
Oddly I've kept lamp eyes on several occasions & seldom lost any as jumpers BUT house is pretty quite & traffic passes several feet from tank; they are terrible gluttons though, when chococlate gouramis were still settling in, the lamp eyes looked ready to burst after feeding, now they only get a nice roundness.
"Green Neons" (only available as wild caught locally) - stay smaller than cardinals, and I really like their iridescence when tank is only lit with ambient lighting .
Very much like your scape!
Take your time looking at fish, maybe get shrimp established first (by a couple weeks) - I have Dicrossus filamentosus (supposedly, but looking more like maculatus now) & they are rather easier with the shrimp than most apistos
