Another plot could be that they time travel to a point where Naruto's parents are still alive. Sarada gets to see a young Naruto and how his family situation was. This could lead to some heartwarming and also tense moments as they try to interact without changing the future too much.
One idea could be that Naruto and Sarada travel back to the time of the founding of Konoha. They could witness the first Hokage's decisions and how the village was initially built. This would give Sarada a new perspective on the history and values of the village.
She could also time - travel to a period when the Uchiha were at the height of their power. Sarada would get to experience the rich Uchiha culture first - hand. She might learn some long - lost Uchiha jutsus that were forgotten over time. And perhaps she'd meet her ancestors and gain a deeper understanding of her family's legacy, which could help her become a stronger ninja in her own time.
In Naruto x Sarada fanfiction, a possible plot is that there is a new threat to the Leaf Village that only their combined skills can defeat. Sarada's intelligence and Sharingan abilities combined with Naruto's vast chakra reserves and Rasengan techniques could make for an exciting battle. Also, it could be interesting if they have to infiltrate an enemy stronghold where they need to rely on each other completely, and in the process, Sarada learns more about Naruto's past and what made him the Hokage.
One idea could be a story where Sarada goes on a mission to Sand Village and meets Gaara. They start to exchange their views on leadership, as Gaara has a lot of experience in leading his village. Sarada could learn a great deal from him about being a responsible and empathetic leader.
Another plot could involve Sarada going on a journey to find out more about her father, Sasuke. She could encounter people who knew Sasuke in his younger days and learn about his past misdeeds and heroic deeds, which would shape her understanding of him and herself as his daughter.
A more emotional plot could be centered around family. Sarada has some doubts about her family, and Naruto and Sakura, having been through their own family - related struggles, could offer her advice and support. They could share their stories of growing up without parents (in Naruto's case) or with a complex family situation (in Sakura's case), which would help Sarada come to terms with her own family issues.
One idea could be a time - travel plot where Boruto and Sarada are sent back to Naruto's era. They could interact with a younger Naruto and help him in some way that changes the future subtly. For example, they might help Naruto with a difficult mission that he barely survived in the original timeline, and this could lead to different relationships in the future.
One idea could be a time - travel plot where Boruto and Sarada are sent back to Naruto and Sakura's genin days. They could witness the early days of Team 7 and get involved in some of their missions, which would change the course of history in unexpected ways.
One idea could be that Naruto travels back in time and gets adopted by a different clan. For example, the Uchiha clan. This would change his whole upbringing and how he views the world. He might learn different jutsus earlier and have a different relationship with Sasuke.
A cool plot idea could be Minato traveling back to his own childhood. He could then use his future knowledge to train himself more effectively, making himself an even more powerful shinobi at a younger age. This would have a huge impact on the future of the Leaf Village as he would be able to better protect it earlier. He might also be able to prevent some of the early tragedies that happened in the village.
One idea could be Tobirama traveling to the future and seeing how his village has developed. He might be shocked by the new technology and the different ninja techniques. Another plot could involve Tobirama going back in time to change a crucial event in Naruto's past, like preventing the Uchiha massacre. Or perhaps he travels to a different timeline altogether and has to find a way back while dealing with that timeline's unique challenges.
