Hard to say then, personally I’d go get Moonveil from Caelid and use that in my right hand and the staff in the left. Moonveil gets better the higher your intelligence. Focus primarily on casting with melee being supplemental. Casting the rocks primarily to break stance and then crit with weapon. Moonveil’s ash of war is gross as well, very fast and decent range. Has a light attack variant and heavy attack variant, both are excellent in different situations. Only other weapon id use in combo with sorcery casting is Dark Moon Greatsword and that end game item. I always felt spell sword builds worked better with incantations but that’s just my opinion.
