So those two are his strongest natures. The issue with the Boruto thing though, is since we don't know Hinata's affinity, we can't use that as proof for Boruto despite them sharing the same nature I guess. Look at it this way, all Uchiha can train themselves into being able to effectively use Fire Release, but their natural elemental affinities could be anything else, as is the case with Sasuke. Boruto didn't inherit Lightning from anyone....
