One common theme is the exploration of her backstory. Since Sephiroth is such a complex character in the original, a female version might have a different backstory or the same one with a different emotional perspective. For example, how she dealt with her discovery of her origin.
Character growth is also a major theme. As they interact, both Naruto and the female Sephiroth are likely to change. Naruto might learn about the darker side of power from Sephiroth, and Sephiroth could learn about the value of friendship and loyalty from Naruto. This mutual growth makes for an interesting exploration in the fanfictions.
Another theme is often the redemption or transformation of Sephiroth. In these fanfictions, the female Sephiroth might have a different path to redemption compared to the male version in the original story. This could involve her relationship with Cloud as a catalyst for change. Cloud, being a more morally upright character, might influence her to turn away from her more villainous tendencies.
One common theme could be power. Both Harry and Sephiroth are associated with great power in their respective universes. So, fanfictions might explore how Harry's new - found connection to Sephiroth affects his power levels or how he uses it. Another theme could be identity. Harry having elements of Sephiroth in him might make him question who he really is.
Isolation is also quite prevalent. Vampires are often solitary creatures, and Sephiroth, being as complex as he is, is shown to be isolated even more so in these fanfictions. He may be shunned by others due to his vampiric state, or he may choose to isolate himself because of his new - found powers and the thirst that comes with being a vampire. And there's also the theme of the unknown. His vampiric abilities and how they work are often a mystery, and the fanfictions usually unfold this mystery gradually.
One common theme is redemption. Many fanfictions try to explore the possibility of Sephiroth finding redemption through his interactions with the original character. For example, the OC might show him a different way of life or values.
One common theme is power. Just like the male Sephiroth, a female Sephiroth in fanfics often has to deal with her immense power. Another theme is identity.

Whether it's with her allies or enemies, the dynamics can be quite different when she's female.
One common theme is loyalty. The little brother is often portrayed as being extremely loyal to Sephiroth, no matter what. Another theme is discovery. The little brother might be on a journey to discover his own identity, which is often tied to his relationship with Sephiroth.
One common theme is redemption. After being hurt, Sephiroth often goes through a journey of redemption with the comfort he receives as a catalyst. Another theme is self - discovery. Through the process of being comforted, he starts to understand himself better.
