One common theme is the exploration of their complex relationship. Since they have an interesting dynamic in the original source, fanfiction often delves deeper into how they interact and understand each other.
You can try searching on FanFiction.net. It has a large collection of fanfictions for various fandoms, and there's a good chance you'll find Ed x Envy fanfictions there.
One common theme is redemption. Since Envy has done a lot of bad things, many fanfics explore the idea of him finding redemption through his relationship with Ed. Another theme is the power of understanding. As they are so different, understanding each other becomes a crucial part of their relationship in these stories.
Well, it really depends on what you're looking for in an Ed x Envy fanfiction. If you like action - packed stories, there could be fanfictions where they fight side by side in battles against other powerful foes. There are also ones that might be a bit more on the dark side, exploring their characters' darker aspects and how they interact in a more morally gray area. Additionally, some fanfictions may focus on their backstories and how those could have led to a different kind of relationship between them in a fictional context.

Another reason is the 'forbidden' aspect of their relationship. Envy is a Homunculus, and Ed is a human alchemist. In the world of Fullmetal Alchemist, such a relationship would be frowned upon. But in fanfiction, this taboo nature makes it all the more exciting to explore. It allows writers to break the norms of the original story and create unique and interesting storylines that involve the two characters defying the odds and coming together in different ways.
There's 'Envy's Redemption in Ed's Eyes'. In this fanfic, Envy, who is usually seen as a villain, has a journey of self - discovery with Ed by his side. It's interesting to see how the story unfolds as they interact more and more.
