Wow, this CAP AT is turning out to be cutting-edge
Anyway, you can look to my last post for my proposed Defining Moves, namely Leaf Blade and Stone Axe. There is some decisions to be had whether Mighty Cleave would be allowed, but if it is, it should probably come with a penalty. The other STAB move that could be considered here is Trailblaze, but considering it's relatively weak BP and having no interaction with Sharpness, no penalty is need. Otherwise, there could be a penalty for having both Sacred Sword + Night Slash for coverage reasons.
