How would you use this space?

Recently remodeled 1960s home. Lots of walnut and white going on. We have this one area in the den - and not sure what to put there. It’s a bench/shelf (quartz) about 6 ft long and 33” deep. Should it be a bench with a cushion? Should I put a plant or a funky light? Some rare and expensive art piece (jk) Anyone have an idea?
