One common theme is friendship development. Since they come from different backgrounds in the Arcane universe, their journey to becoming friends or even closer is often explored.
A great fanfiction idea is one that delves into their relationship dynamics. For example, how they deal with their differences in social status. Caitlyn being from the upper class of Piltover and Vi from the undercity. It could show how they overcome these barriers and grow closer through shared experiences and mutual respect.
A common theme is also the exploration of their backstories. How Vi grew up in the undercity and Caitlyn in Piltover, and how these different backgrounds shape their characters and interactions. Some fanfics also focus on the power dynamics between them, considering their different skills and positions in society.
Fanfiction.net is also a good place. There are many writers who contribute to the Arcane fandom there. However, the quality may vary, so you might need to skim through a few stories to find the really good ones about Caitlyn and Vi.

Shenzhou-6 was China's second manned space mission, and it was also China's second spacecraft to carry astronauts. It was launched from the Jiuquan Satellite Launch Center on October 12, 2005, and successfully landed in a predetermined area in central Inner Mongolia on October 17. Shenzhou VI's mission was to launch and operate the two-person spacecraft safely. It also conducted scientific experiments on bone cells on the Earth's surface, cardiovascular medicine, digital photographs, and spacecraft testing. The success of this manned space flight marked the smooth start of China's manned space project and was one of China's major achievements in the aerospace field.
One common theme is loyalty. Jinx is extremely loyal to Silco, and this is often explored in fanfiction. For example, in many stories, Jinx will go to great lengths to protect Silco or carry out his orders, no matter the cost.
There's also 'Jinx's Redemption in Silco's Eyes'. This fanfic focuses on Silco's perspective of Jinx. It explores how he sees her potential and how he tries to guide her, while also dealing with his own ambitions. It's a really interesting take on their relationship.
Some 'Silco fanfic' might be about alternate universes. In one such story, Silco could be a hero instead of a morally grey figure. He might use his power and intelligence to bring about positive change in Zaun in a completely different way than in the original story.
