Electric/Water,
Steel/Fairy
Poison/Dark
Offensively:
Dragon/Fire
Steel/Fairy especially is objectively the single best defensive typing in the entire game.
something like 11 resists, 2 immunities, and only 2 weaknesses (fire/Ground). Its as strong as the old Steel/Psychic except if Psychic was immune to dark instead of the other way around.
Electric/Steel still has the most resists, though, but only 1 immunity compared to 2, and is double weak to Ground while also being weak to Fighting, which Steel/Fairy isnt.
