Can you show all four walls in this room? It is hard to make suggestions out of context.

Obviously a massive piece of great art would be nice, but for most people that is not in the budget.

Is there room to scoot the table towards the photographer and put a long slim console against the wall?

I would do this install, perfect with your beams.

You could use peel and stick wallpaper; then there is pole wrap that you can purchase just about anywhere; and of course, panels.
