Has anyone found spells/abilities or feats or class traits or weapon types that allow your character to use Wisdom/Intelligence/Charisma instead of Strength/Dexterity for weapon modifiers/rolls (damage & hit)?
Not any class can do this...just proficiency with a weapon type isn't enough. Warlocks have the Pact of the Blade which allows them to use their charisma modifier instead of strength, and there are some weapons that naturally allow any character to choose to use their dexterity modifier instead of strength if they wish. But options for this kind of stuff is very limited, the same as in D&D. Wizards are just not made to be swinging greatswords and I don't believe there is any way for any class to apply the intelligence modifier to weapon attacks that I can think of.
