More on the smooth jazz side, but give David Benoit a try. American Landscape or A Midnight Rendezvous to start.
Or maybe some of the recent stuff from Emmet Cohen. Uptown in Orbit.
Till Bronner was mentioned above. There’s a great album by Till and Bob James - On Vacation. Or just about anything Bob James.
Edit: I see you’re already familiar with On Vacation. I’ll also add Bill Evans - You Must Believe in Spring.
