I know pawns will learn the best way to fight a monster by being shown by you, have another pawn show them, or knowledge scrolls you can use on your pawn. You can check their knowledge on a monster and it ranges from 1 to 3 stars.
I will end up on a sorcerer and my pawn will end up a mage for healing. And I will hire fighter and ranger pawns then.
