There are no regular buffs for attributes. These attributes are only keywords for other characters' buffs. For instance Iruka buffs Konoha's ninjas, and Konan buffs akatsuki. So you can check whether other characters will receive these buffs just checking their attributes, without google or knowledge of naruto franchise. There are also some other more deep meanings, like whether Minato is a sage or not from the game's standpoint. Edo is obviously a sage, but is jonin version a sage too? So instead of guessing or trying, you just check character's attribute and learn this info right-away.
