One common theme is the struggle with knowledge. Since Naruto can read the future, he has to decide what to do with that information. For example, if he sees a friend's death in the future, should he try to change it? Another theme is the alteration of relationships. His knowledge of the future can make him act differently towards his friends and enemies, which can strain or strengthen those bonds. Also, there's often the theme of fate vs. free will. Does seeing the future mean they're doomed to that fate or can they change it?
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.
They might be shocked. For example, Naruto himself, if he reads about future threats to the village in the fanfiction, he would probably start preparing immediately to protect his friends and the Hidden Leaf. It could change their present actions as they try to avoid bad futures or work towards good ones.
In a 'Naruto travel to the future fanfiction', Naruto would adapt through his strong sense of curiosity. He would be eager to explore every new thing he sees in the future. His resilience would also play a big role. If he encounters difficulties, like not understanding how a particular future - tech works, he won't give up. Instead, he'll keep trying until he figures it out. And his ninja training gives him discipline. He would use this discipline to study the new ways of life in the future, from the social norms to the technological advancements.
Naruto would be excited and ready to face whatever comes. He's always been positive and believing in his ability to change things. So, he'd see it as a challenge to make the future better.

They might be amazed at the power and creativity behind it. Maybe Naruto himself would be excited to see how the next generation has advanced the art of ninjutsu.
Obviously, Naruto himself is the most affected as he has to deal with the knowledge of the future. But his friends like Sasuke, Sakura, and Kakashi would also be deeply affected. If Naruto saw a future where Sasuke was in trouble, he would do everything to change it, which would impact Sasuke's life. Sakura, being Naruto's teammate and also caring about Sasuke, would be involved in any plan Naruto made. And Kakashi, as their sensei, would be there to guide and support them through the changes Naruto tries to make based on his future vision.
There are quite a few things. For one, he could teach past Naruto about the deeper secrets of the Uzumaki clan. Since Future Naruto has explored more about his heritage. He could also give tips on handling the Kyuubi's chakra more smoothly. Maybe some new jutsu combinations that he discovered over the years. And not to forget, how to better read an opponent's moves during a fight, which is a skill he would have refined over time.
Yes, there is. The Naruto fandom has a strong foundation in the original anime and manga. Even after the last fanfiction, fans will still love the characters, the storylines, and the world.
