Paladin in BG3 - which oath and multiclass is worth it?

vengeance if you want damage, devotion if you're tanking for the party. ancients gets overlooked but its aura later on gives resistance to spell damage, which saves a couple of nasty late fights. oathbreaker isn't a pick at level 1, you only get it by breaking your oath. multiclass, the two people actually run are paladin 2 into sorcerer, so you smite off sorcerer slots, or paladin into warlock with pact of the blade so you attack with charisma and only need one stat. whatever you do, take paladin to 5 for extra attack before you dip, and 6 if you can stand it. aura of protection adds your charisma to everyone's saves nearby and it's the best thing the class gets.
