One main theme is often power. Exploring the potential power of Rin's Sharingan, how it compares to other Sharingan in the Naruto world. Another theme can be sacrifice. Given Rin's fate in the original series, fanfictions may explore the sacrifices related to her Sharingan, like she might have sacrificed her own well - being to protect others with its power.
One popular 'naruto rin sharingan fanfiction' is 'The Rin's Legacy'. It delves into how Rin's Sharingan could have had a greater impact on the Naruto universe if she had survived.

They might initially struggle to control it, but as they learn more about it, they become a formidable force. For instance, they could use the Sharingan's genjutsu abilities to deceive opponents in the Fairy Tail battles.

A great fanfiction concept might be that Naruto somehow gains the Sharingan and Susanoo abilities. Maybe through some sort of experimental jutsu gone wrong (but in a good way).
