And since your husband is handy, I'd get him to add under cabinet lighting. That will be so nice to work with, and will highlight your new counter and backsplash.

I like white cabinets. If they are in good shape which from the picture they look like they are then I would leave them as is. Maybe changing the hardware would update them and that is an easy fix and budget friendly. Laminate countertop in a granite looking finish would be inexpensive along with ceramic tile for backsplash. You might want to consider changing the wall color to complement the countertop and backsplash.

I actually think the white cabinets work great against the white countertop. Perhaps changing the faucet and updating the hardware would be enough. Also I would lighten up the wall color to provide a freshened look.

What about popping colour on to doors and drawers and leave sides white.?

Change hardware and do granite look rust oleum to countertop also
