Maybe the Phoenix Force is drawn to Naruto because of his strong will. In the story, the Phoenix Force has been searching for a worthy host for a long time.

In this fanfiction, Naruto's encounter with the Phoenix Force might be accidental. He's exploring an ancient ruin when he stumbles upon an artifact that contains the essence of the Phoenix Force. At first, he doesn't understand what it is, but as he starts to feel its power, he has to make a choice: to embrace it or to leave it be. If he embraces it, he'll have to face the consequences of having such a powerful and dangerous force within him. He'll also have to deal with the political implications in the ninja world, as other villages might see him as a threat with this new power.
Well, one idea for this fanfiction could be Naruto somehow getting connected to the Phoenix Force. Maybe it's during a mission in a strange dimension where he discovers the power of the Phoenix Force.

And this new power could also attract new enemies who are after the Phoenix Force.
He might need to train a lot. Just like he trained to control the Nine - Tails' chakra. He could start with small amounts of the Phoenix Force's power and gradually increase his control.
If Naruto got the Phoenix Force in fanfiction, his appearance might change a bit. Maybe he'd have some sort of fiery aura. His personality could also be affected.

Also, he might be able to use the force to perform even more acrobatic moves during battles, making him even more formidable against opponents like Sasuke or Orochimaru.
One possible new jutsu could be the 'Force - Nature Manipulation'. Naruto loves nature and is already good at using nature - based chakra. With the force, he could go beyond just using chakra from nature. He could use the force to actually control natural elements like waterfalls, trees, and rocks directly. For example, he could make a whole forest move to his will, trapping his enemies or creating barriers. This would be a very unique and powerful jutsu that combines his ninja skills with the power of the force.
If Naruto were a master of the force in fanfiction, it would change the whole Naruto universe. He might be able to levitate and move objects with ease, which could be a huge advantage in battles.
