Aiya, this question isn't simple ~ But I still have many recommendations! For example,"Koba: From the moment I met Teruya Otsuki." This doujinshi novel was about the night of the nine tails. The main character traveled to the Naruto world and became Teruya Otsuki's husband. The two of them gave birth to Koba Otsuki and Naruya Hamura together, and then a fantastic and cute story began. In addition, if you want to try the novel "Naruga's Wife is Teruya Otsuki," it was also a story about a man who traveled to become Teruya's husband. I hope you will like my recommendation. Muah ~
Yes, there are likely many Naruto fanfictions that involve Kaguya and explore her various characteristics. Some might focus on her power, her origin story, or her role in the Naruto universe. However, without specifically searching through fanfiction databases, it's hard to be more precise.
Kakashi can be a popular character too. His wisdom and combat skills can be useful in fanfic scenarios involving Kaguya. He could be a mentor figure to Naruto, guiding him in dealing with Kaguya - related threats or helping to decipher ancient ninja knowledge related to Kaguya.
Yes, there are likely some fanfictions that explore a special connection between Naruto and Kaguya. In some fanfictions, authors might create scenarios where Naruto, due to his unique abilities and kind - hearted nature, manages to reach out to Kaguya in a way others couldn't.

Kaguya Otsuki is often a very popular character. She is such a powerful and mysterious figure in the Naruto lore, and in fanfics, authors can explore her motives and past more deeply.
One great 'Naruto Otsuki Fanfic' is 'The Otsuki's Legacy'. It explores the backstories of the Otsuki clan in a really interesting way. The characters are well - developed and it adds a lot of depth to the Naruto universe that we don't see in the original series.
