One idea could be a story where Peridot tries to prove her worth to Yellow Diamond in a non - traditional way. Maybe she discovers a new form of energy on Earth that could benefit the Diamond Authority, and she has to convince Yellow Diamond to give her a chance to explore it further.
Redemption and growth are also themes. Maybe Peridot helps Yellow Diamond see a different side of things, leading to her becoming a more empathetic character. Or vice versa, with Yellow Diamond guiding Peridot in some way. It could be about them growing together in an unexpected relationship.
Their relationship could develop through mutual discovery. For example, Peridot could show Yellow Diamond the unique aspects of Earth that she has come to appreciate. Yellow Diamond, in turn, could share some of her knowledge of the Gem Homeworld with Peridot, creating a bond based on the exchange of ideas.
One common theme is power dynamics. Since Yellow Diamond is a very powerful figure and Peridot is much lower in the hierarchy, their interactions often explore this difference in power. Another theme is redemption. Sometimes, the fanfics will have Yellow Diamond seeking redemption for her past actions, and Peridot plays a role in that process.
I've read a 'peridot x yellow diamond fanfic' where it was set in a post - war scenario. The fanfic delved deep into how they both had to adjust to the new world order. Peridot was trying to find her place among the gems, and Yellow Diamond was dealing with the loss of her authority. Their relationship in this fanfic was a slow - burn type, starting from mutual suspicion to gradually understanding each other. It was really well - written with great character development.

There's also the 'secret relationship' trope. Considering their status in the Diamond Authority, a relationship between them might have to be kept a secret at first. Fanfictions might explore the challenges and thrills of keeping such a relationship hidden from the other Diamonds and the rest of the Gem society.
The world - building aspect. The Gem world they exist in is already so rich. Fanfiction writers can expand on it even more when it comes to Yellow Diamond and Yellow Pearl's relationship. They can create new scenarios, new power struggles, or new forms of loyalty that add depth to the already fascinating world of the Gems.
Yellow Diamond in fanfiction often has to handle difficult choices regarding her rule and the well-being of her subjects. She might encounter rebellions or have to make tough decisions to protect her domain.
One popular theme could be Yellow Diamond's relationships with other characters in the original story. For example, her interactions with the Crystal Gems or other Diamonds. Another theme might be exploring her backstory, like how she rose to power and what events shaped her into the character she is. Also, stories could focus on her role in the Gem hierarchy and how she manages her colonies.
