I'm not sure about a specific 'naruto read the future fanfiction' but you can start by looking on platforms like Fanfiction.net or Archive of Our Own. Usually, fanfictions with such a concept will have Naruto either through some magic or special jutsu start seeing the future. This then leads to him making different decisions in battles or in his relationships, like with Sasuke or Sakura.
Well, a really interesting 'naruto read the future fanfiction' could be one where Naruto's future - seeing ability is tied to his nine - tailed fox chakra. As he delves deeper into understanding the fox's power, he unlocks this ability. It might show him seeing the future of Konoha, his friends' fates, and how he has to change things to avoid a dark future for everyone. There could be intense moments where he has to decide whether to trust his visions completely or not.
