With a Hyuga you'd be able to get Ninjutsu, Genjutsu and Taijutsu + Basic 5 elements (Fire, Water, Wind, Lightning and Earth) + Jyuuken which is the Hyuga techniques basically.
The only things which are restricted are things which are overpowered or things which are only specific to other characters. For example Mokuton is specific to Hashirama and Yamato and so you woulnd't be able to learn it.
