Well that sounds a pretty interesting concept. A separate post question on this question may be needed but some thoughts to kick off. Some are probably already obvious and I have never kept cichlids (or at least can't remember).
I'm ignoring stock limits - just in case not seen this website will help with that http://www.aqadvisor.com/
On mine I tried to match the fish to my tap water specs (however I doubt many of mine are caught from the wild) and to each other. I ended up going in and out of a lot of fish shops and using an aquarium app to research. On colour I've found that a school of say orange'ish rosy barbs makes a nice contrast to black mollies so it can be worth looking at fish vs fish vs background.
Lower level, plecos like the bristlenose catfish will love the wood and spring to mind.
Tetras have nice colours, lately I'm taken with cardinal tetras or I saw rummy-nose tetras in the shop today that I thought nice.
