I’d keep it simple due to the size, style, and being so close to your shelves of decor .... and I’d want some varying heights.

I’d remove the burlap runner and either have no fabric or use a decorative placemat (beaded, woven, etc) or macrame runner (folded artfully and having some fringe hanging off the front). I think the above ideas would tie in well with your other decor, and be an eclectic contrast to the modern console (and provide a nice softness and texture). Example:

For decor, I’d lean a framed piece of art on the wall, and just add an interesting bowl. Showing these just for the art idea, not accessories—

Love these bowls:

Do some searches for decorating consoles for lots of ideas. :)
