I bought a nice original 2 piece wood center console trim plate for my car off Ebay but it has 2 extra holes for switches that my car doesn’t have. Does someone sell blanks to fill these holes? If not, what switches should I use that would seem the least obtrusive or functional. The car has three switches near the top for defroster, central locking and hazards plus now an extra hole, and there is an extra hole to the left of the ashtray which I think some cars have for an ASR switch.

You can find this info in your owner's manual, if you have one.

I suggest a scrap yard, when you see the price for some of the switches the panel will seem cheap!
