Autoglym Super Resin Polish, 1Z Metallic Polish, even stuff like VM or Meg's #9 and 3M SMR can work on wood that's not too scratched up; IME the same products that fill micromarring on regular paint do the same thing on interior wood. And yeah, you can polish it like paint too, but remember that it's soft and thin by comparison; I've gotten to where I think twice about going for perfection as I sure don't want to have to have the wood refinished.
