My favorite houserule is that casting classes that get cantrips gain the general magic cantrip related to their class for free. For arcane that means prestidigitation, druids=druidcraft, clerics=thaumaturgy.
Those are mostly flavor and RP cantrips that make the world and character feel more magical. It also frees up the PCs to select more unusual cantrips.
