You could add shelves and/or cabinets:

If you don’t want that, you could wallpaper above it and add art, a mirror, shelves on one side, etc. Some more ideas:

I’d want lighting, either lamps or sconces … maybe see what an electrician would charge for wiring? (I’m married to one, he does this sort of thing often.)

Thanks so much for your suggestions! We’ll probably start with some decor first, and then maybe add the side cabinets in the future. A big, blank slate is not easy for me!

I totally understand!

I do like the idea of a cool wallpaper, though. Either way, once you get in there with furniture and such, you’ll see what else is needed and wanted. It’s a great feature! I really like the cabinet color.
