Lance Switch Skills ?

Base Rise High rank player here. I wanna learn Lance but cant fathom which switch skills are "better" depending on the guard level and generally. My build has Guard level one. Maybe somebody here can give me some advice, thx in advance. (Guard / Insta-Block) (Dash Attack / Shield Charge) (Anchor Rage / Spiral Thrust)

Edit: thank you for your input and long essays. I will try using all unlockable switch skills (insta block/ shield charge/ spiral thrust) and become a true tank.
