Well, after getting a lot of good ideas, I followed Eric B's route on the glovebox door. Light sanding, stain, varnish. Looks pretty good and will match the instrument panel and switch panel when I get to them. Teak doors and trim also got a lot of sanding and varnishing, just installed this weekend and launched the boat.
I have attached before and after pics of the glovebox door and finished shots of the teak. The cabin door pic is rotated and I don't know how to fix that, sorry
Thanks for all the advice, especially you, otterhound.
