There might be a fanfic where Sakura discovers a hidden area in Konoha filled with sakura trees that have magical sakura leaves. These leaves give her special powers, but she has to keep it a secret. It could be a really exciting fanfic with elements of mystery and adventure. You can look for such concepts on different fanfic websites.
I'm not sure about a specific one off the top of my head, but you can try searching on fanfic platforms like Archive of Our Own. Just type in 'Sakura leaves Konoha' and you'll likely find some great ones.
One possible 'sakura is not from konoha fanfic' could be 'Sakura's Alternate Origins' where she hails from a hidden village far away. It explores how her different upbringing changes her character and her relationships within the Naruto universe.
Sasuke might initially be shocked. He has always seen Sakura as someone connected to Konoha, so her leaving would be unexpected. He could be concerned about her safety, especially if she leaves without proper preparation or protection.
One interesting Sakura leaves Konoha fanfic could be about Sakura using the symbol of sakura leaves in a new jutsu she develops in Konoha. It might show her growth as a ninja.
She might be shocked at first. Sakura has always known Naruto as someone who is very attached to Konoha. If his leaving is because of her, she could feel guilty. She might try to stop him, asking him why he's doing this and telling him that he doesn't have to go.

For Naruto, it would be a big shock. He's always seen Sakura as an important part of the team. He would probably feel guilty, thinking he might have done something wrong. Sasuke might be more reserved in his reaction, but deep down, he would also feel the loss. Kakashi would be worried about her safety. The other ninja in Konoha might start to question the unity of the village if someone like Sakura, who was so well - known, left. And the young ninja who looked up to Sakura would be disappointed and might even lose some motivation in their training.
Naruto would be devastated. He has always considered Sakura as a dear friend and teammate. He would probably try to convince her to come back at first. If that fails, he might see it as his mission to bring her back by force if necessary, believing that she has been led astray. Sasuke, on the other hand, might have a more complex reaction. He has his own issues with Konoha, so he might understand Sakura's desire to leave on some level, but he would also be suspicious of her motives for joining Akatsuki.
Well, I've read one where sakura is from a small, secretive clan outside Konoha. In this fanfiction, her skills are shaped by the different values of her home place. She might be more independent and less influenced by Konoha's mainstream ninja culture, which makes for an interesting story as she interacts with the familiar Naruto characters.
One popular 'sakura leaves with itachi fanfiction' could be 'Sakura's Encounter with Itachi under the Sakura Leaves'. In this fic, the author beautifully describes the scene where Sakura and Itachi meet among the falling sakura leaves, creating a very poetic and somewhat melancholy atmosphere.
One idea could be that Sakura leaves Konoha to study a rare form of medical ninjutsu in a far - off land. During her journey, she discovers a new type of chakra that has the potential to revolutionize the medical field in Konoha. Another plot could be that she leaves because of a misunderstanding with her friends in Konoha, and while away, she has to fight against a group of rogue ninjas who are after a powerful artifact she accidentally comes across. A third plot might be that Sakura leaves to find a cure for a strange illness that has started to affect the ninja in Konoha, and her travels take her to places she never imagined and she meets old enemies who become unlikely allies in her quest.
