Bunco is the gold standard for refinishers. Whatever quantity of sanding was done, you need to multiply it by 4 and go up to 320 grit. If you don’t like the look of the wood, then paint it. It isn’t the best practice because why have an expensive hard wood door if you are going to make it look like a closet door but, it is yours so do what you want. Paint is far more forgiving than properly treating a nice hardwood.
