One common theme is power and leadership. Since Byakuya is a powerful character in the original Bleach series, in the fanfictions with a female version, she is often depicted as a strong leader. Another theme could be relationships, whether it's her family relationships or romantic ones. For example, how she interacts with her sister in a different light as a female character.
Many female Byakuya Kuchiki fanfictions explore the theme of identity. How does being a female change her role in the Soul Society? Does she face different challenges or opportunities? Also, there's often a theme of loyalty. Just like in the original, she is loyal to her clan and to the Soul Society, but it might be expressed in different ways. Some fanfictions might also explore themes of justice and honor, which are integral to the character of Byakuya Kuchiki in the first place.
A significant theme is also the struggle for acceptance. In a male - dominated Soul Society, a female Byakuya Kuchiki might have to fight harder to be taken seriously. This can lead to stories of her proving herself in battles, in political situations, or in social interactions. The theme of change is also there. How does her presence as a female change the dynamics of the world around her? It could be the way other characters interact with her or the way the Soul Society as a whole evolves because of her.
