One possible plotline could be that fem Naruto, being a big admirer of Uchiha Rin, tries to follow in her footsteps. Maybe she wants to learn the same jutsu or have a similar impact on the village as Rin did.
One way to find good 'fem Naruto is a Uchiha Rin fanfiction' is to join Naruto - related fan communities on social media platforms like Reddit or Discord.

In a fanfiction world where Naruto and Rin have a baby, it could be a very interesting story. Maybe the baby would inherit Naruto's positive attitude and Rin's kindness. The story could explore how they raise the child in a world full of challenges and ninjas.
The Uchiha might initially be filled with anger. Their trust in Naruto, if it was there before, would be completely shattered. They could start to plot revenge against Naruto, believing that he has wronged them. This could lead to a lot of tense moments in the fanfiction as the Uchiha gather their strength and resources.
Kakashi is known for his laid - back yet highly skilled nature. His influence on Naruto could be in terms of teaching him to be more strategic in battles.

I'm not sure about the absolute best, but some authors might stand out if they have a deep understanding of both Naruto's and Rin's characters. Those who can capture Naruto's determination and Rin's kindness in their writing would be great. Look for authors who have a lot of positive reviews on fanfiction platforms.
There are indeed such fanfictions. In these stories, Rin's survival can have a huge impact on the other characters. For example, it could change Obito's path completely.

If Naruto and Rin had a baby in fanfiction, it might have unique abilities. Since Naruto has the Nine - Tails' power and Rin was a skilled kunoichi, the baby could inherit some extraordinary skills. For example, it could have a special form of chakra control.

Since Naruto and Rin are from different storylines in a way, it makes for an interesting exploration of how their personalities might interact. For example, Naruto's determination might contrast or complement Rin's own qualities.
