If you want to go the suboptimal route and use the staff one handed with a multiclass or feat usage for a secondary stat to attack with I say more power to ya.
As long as you as a player realize you’ll not (nor should you) be as viable as an dedicated martial character (or an optimized bladesinger) in melee combat.
personally I’d go the monk route but with shillelagh stats- since you can’t use the martial arts if you’re wearing light armor, you’re going to need to have a high wisdom regardless if you want to have a halfway decent AC.
you’re still throwing points at a stat you don’t really care much about except to twirl your stick, but at least you don’t need to waste an action to make it happen.
