Looking for input on kitchen cabinet space

Okay. I’m new to cabinetry, so I thought I’d seek out some suggestions.

The house was built in 1957. The cabinets are largely original along with the stainless countertops.

Wife wanted to remove the island cabinets to make it more comfortable as well as opening up the space. We’re going to be installing a stainless range hood.

Unsure what to do as far as where the cabinets were mounted on the wall. I’m thinking something should go there to balance it out, but I’m not very creative.

Any ideas would be appreciated. Thank you.

I’ll attach before as well as current photos.
