Fine wet n dry and 0000 wire wool for the neck, do you think a light slurry might help smooth the grain? and a light Danish Oil or Waxing.
As for the body? Blue Car T Cut type stuff, more as a cleaner! and then as is?
Toothpaste is a mild abrasive, maybw a light going over on the headstock.
Looks nice n thin, could quite fancy one of them, acoustic bridge gives it a simple look rather than going large with a stop tail or 3 point.
Flats?
