For Naruto and Sarada, Naruto could become a more active mentor. He could take Sarada on special missions and during those, they could bond over their shared love for the village. Naruto could also share his experiences as an orphan, which would make Sarada feel closer to him.
Sakura and Sarada's relationship could be developed by Sakura teaching Sarada more about medical ninjutsu. They could have mother - daughter study sessions where they not only learn about the techniques but also open up about their feelings. This would strengthen their bond on both a professional and personal level.
All three of them could be involved in a community project in the village. Naruto's leadership skills, Sakura's medical knowledge, and Sarada's enthusiasm could combine. Through working together on this project, they would understand each other better, and their relationships would grow. For example, they might be building a new hospital in the village, and each would contribute in their own way while also learning about each other's strengths and weaknesses.
