According to the information you provided, the novels with the main character being the reincarnation of the Sage include Dao Seal and Tianmang Transformation.
In " Seal of Dao," the main character Jiang Xiaofan was a mortal who accidentally obtained a fragment of the seal. He cultivated the Wugu Sutra of Buddhism and Taoism, traveled in the Ziwei River, crossed the Milky Way, and was invincible under the starry sky. He proved the supreme Great Dao with his own body. He was the reincarnation of one of the nine heavens, the Sage.
In " Tianmang Transformation," the main character, Jiang Fan, was also the reincarnation of Shengtian. The novel told the story of Jiang Fan transmigrating to the Primordial World and becoming one of the Nine Sons of the Heavenly Dao, Shengtian. He fought fiercely with the other eight emperors.

Well, it depends on the specific fanfic. Some fanfics do portray Naruto as the reincarnation of the Sage. This concept can be used to explore different plotlines. For example, it might explain some of his unique abilities that seem to come out of nowhere in the original story. It also allows the author to create new relationships and power dynamics within the Naruto universe.
The novel I recommend to you is "The Ghost Who Knows Taoist Arts", a fantasy immortal cultivation novel. The protagonist is in the process of reincarnation and falls into all kinds of dangers and doubts. He must work hard to cultivate and save mankind. I hope you like this fairy's recommendation.

The fantasy novels that were transmigrated were more popular, such as Douluo Continent, Battle Through the Heavens, and Martial Universe. These novels described the growth and struggle of the protagonist in the other world. Through continuous cultivation and improvement of strength, he finally realized his dream. Some of the novels also involved the concept of reincarnation, where the protagonist was born into another world and gradually grew into a powerful character through continuous cultivation and adventure.
The plot of such a fanfiction might start with Naruto experiencing strange visions or dreams related to the Sage. As he investigates, he realizes his reincarnated status. Then, it could be that he has to learn to control the Sage's powers, which are far beyond what he has known before. This could lead to him having to re - evaluate his own ninja way. His friends might be initially skeptical but then come to support him. There could also be antagonists who either want to use Naruto's newfound connection to the Sage for their own evil purposes or who are afraid of the power he might gain and try to stop him from fully realizing his potential as the reincarnation of the Sage.
Well, power progression is a big theme. Since they are a sage reincarnated, they gradually unlock and develop their powers as the story unfolds. Then there's the theme of friendship or comradeship. They meet different characters along the way and form bonds with them. And of course, the theme of facing destiny. They are in this new world for a reason, and they have to face whatever fate has in store for them in this reincarnated life.
Hehe, I recommend "Unparalleled Demon Emperor" to you. It's a fantasy novel. The protagonist is the number one assassin on Earth. He possesses the body of a good-for-nothing son-in-law and pursues the pinnacle of martial arts. In the end, he becomes the Supreme Demon Lord. It was very suitable for the theme of reincarnation in another world! I hope you like my recommendation. Muah ~
