It's personal preference really, but don't try anything too demanding. I'd put a flat piece of DW with some moss tied if you considered a shrimp tank. If you consider it a planted tank with shrimps then you can scape it any way you like.
One suggestion if search youtube with phrases like "CRS tank", "CRS Fluval Edge". That should give you some ideas.
