Greeting Scott,
Sounds like you already have had quite experiences with freshwater aquarium. Since you don’t have a specific question I’ll just type whatever pops up in my head.
Since you have a large tank, I think ensuring that water parameters stabilize first, with a fully established ecosystem, is really important before introducing any fish into the tank. This way, it helps you narrow down your choices of fish and also avoids the stressful process of altering water parameters, especially in a big tank like this. It's going to be a slow process, but no rush – don’t add too many fish at one time.. always monitor their reaction and behavior
Plants: Anubia species, Java fern, Java moss, dwarf sword, chain sword, are all good for low lech and low maintenance. Corkscrew vallis, creeping rush are really nice background plants.
Fish: For a peaceful tropical community tank, you may consider neon tetras, cardinal tetras, or ember tetras. Male guppies also good choice to add color and activity in your tank. Cherry shrimp should do well for this setup as long as there are plenty of hiding spaces among your plants.
Most importantly, enjoy the process and the beauty of this rewarding hobby! Good luck and have fun!
