The only ones who have plot relevance are Kaguya and Tsunade. Kaguya ia a plot device that came out of nowhere because Kishimoto didn't know how to kill Madara, she sucks narrative wise.
The others are just wasted potential
The minimum Sasuke should do is be the babysitter of Naruto's son after he forgiven him and saved him. Hinata owns nothing to Sasuke. In the gaiden Sarada ran away and was almost killed by Sasuke, the situation was more focused on Sarada specially because Sakura did a lot of shit too like...
She would be killed imetiately because she is dumb and her body wouldn't handle even two tail. She would kill Sasuke kun too because she would awaken nine tails when she is rejected or other girls are next to him
