Not sure of your space, but perhaps a bench against the wall/window and a white table.

as an eg:

i think a bench or settee would look nice under the window

ignore the chairs on this one. While I love her style, the chairs are my least fave.

I think you could do any type of rustic type of wood table. I'd stay away from the mass produced traditional looking dining tables.

Any recommendation on where to purchase the tables described?

check local carpenters as they often make some of these. otherwise, search "rustic dining table', 'reclaimed wood table' or try, 'farmhouse dining table'., 'trestle dining table', etc. you should see plenty of options. for the bench seating like shown, look at settees, or dining table bench seating.

they have some here on Houzz. see if you like any of these

Please no bench IMO the most awful seating at any table. We have no idea of the style of the rest of the house so maybe share that with us.

I think stools or wood chairs would look great in your kitchen!
