One interesting idea could be that Luffy has to rely solely on his Haki and physical training, making him even more of a badass in combat. He might develop unique fighting styles that we haven't seen in the original story where he had devil fruit powers.
Well, in the original One Piece, Luffy's devil fruit powers are a huge part of his identity and his combat capabilities. But in this fanfiction, without the devil fruit, his physical strength and Haki would be emphasized more. His fights would be more about pure skill and strategy rather than relying on the strange and wonderful abilities of the Gum - Gum fruit.
I recommend 'The Legend of Celestial Immortals'. The main character of the novel, Mo Xian, traveled to the Firmament World and became an outer disciple. He loved farming. While the various big shots were fighting over the Ginseng Fruit and Lingzhi, Mo Xian was using these precious spiritual medicines to feed sheep or rice. In the end, through their unintentional actions, all the important figures came over to beg Mo Xian to exchange for the spirit herbs. If you're interested in this novel, you're welcome to read it. I hope you'll like this fairy's recommendation.

The Fire Devil Fruit could make Naruto more confident. Having such a powerful ability would give him an edge in battles and make him feel more capable. This newfound confidence could also change how he interacts with his friends and allies. He might be more assertive in leading them.

First, give the OC a unique backstory. Maybe they got the Absorption Devil Fruit by accident, like finding it in a hidden chest on an abandoned island. For their appearance, you could give them markings on their body that glow when they use their power. In terms of personality, make them curious. Since they can absorb different things, they would always be eager to test the limits of their power. For example, they might be the type to immediately try to absorb a strange new substance they come across.
If Naruto had the Fire Devil Fruit, his combat style would change drastically. He could combine his existing ninja skills with the power of the fruit. For example, he might be able to infuse his Rasengan with fire, making it even more powerful. Also, his mobility could be enhanced as he could use fire to propel himself in new ways. This would make him a more formidable opponent in battles against strong foes like Sasuke or Pain.
