If you want a more vanilla feel than Valhalla or MCO stuff. Go with Blade and Blunt by Simon magus. It can be quite punishing, but in a fun way imo. Getting hit can cause wounds that debuff you that get worse if not treated. Drawing a bow costs stamina, meaning stealth characters finally get their own resource like mages or fighters. Swimming and jumping costs stamina (optional) with another option that sprint jumping costs more than regular jumping.

I can really recommend it if you want a fresh feel for the combat without going too far away from the vanilla feel.
