The banjo looks really nice with the walnut caps and the monogram looks clean.
I suggest start with the tall bridge. It’s a matter of preference really, the taller bridge will have the strings higher off the neck but there is less likely going to be any fret buzz problems even in higher humidity conditions which could cause the skin to temporarily sag a little. If it plays better with the shorter bridge, go for that and keep the taller if ever need to counteract any humidity sag
