I would not put anything up there unless you need more storage then I'd add a set of cabinets to the ceiling if you can get the exact same style that you have currently. You have a very sleek modern space and I would not clutter it up visually with a lot of different elements. Love it.

I would possibly add cabinets to the top. Can you get a KD to do a mock-up?

I have someone looking at them in a few weeks.. after lockdown

Cover the tops with paper towels (no one will know) and replace them after awhile otherwise cooking grease will make a film on top. No decorations. They look nice just the way they are.

If you cannot match the cabinets to add more of them above the existing, you could do something like this, if you want a different look:
