If you want to keep it simple go for osmo polyx, it's spendy but basically you can't go wrong with applying it, it's food safe and looks great.
There a some very dry (but interesting) books that run to hundreds of pages of text about nothing but finishing wood. Its a pretty deep rabbit hole. If you have the time and want to make it look extra special then I think a French polish would suit.
Any recommendations for finish to use? Not got a clue.
Was thinking maybe brass just for flash next time.
