I really like 'The Protector'. In this fanfiction, the author does an amazing job of portraying Eliot Spencer's character. The relationship between Eliot and the reader develops in a very natural way, with the story taking place in some exciting and dangerous scenarios. It has a good balance of action, drama, and romance.
The setting also matters. Whether it's in a city full of crime or a remote location, the setting can add to the mood. In some fanfictions, the dangerous settings make Eliot's protection of the reader even more significant. For instance, in a story set in a war - torn area, Eliot's ability to keep the reader safe while also dealing with his own demons makes for a great read.
A common theme could be the exploration of their different personalities. Spencer Reid is often portrayed as highly intelligent and a bit socially awkward, while Eliot Spencer is more of a tough, action - oriented type. So, fanfics might focus on how they interact and learn from each other.
One great place to start looking for Spencer Reid x Eliot Spencer fanfic is Archive of Our Own (AO3).

You can also try searching on Tumblr, as some fans may share their favorite fanfics or even write short snippets themselves.
One common theme could be his physical recovery. Since he's often in action - related scenarios, getting hurt physically and then having to heal. Another theme might be emotional hurt, perhaps related to his past or relationships within the story's context.
There are quite a few amazing Spencer Reid x Reader fanfictions. 'A Chance Encounter' is a really nice one. It starts with a simple encounter between Reid and the reader and then develops into a deep and meaningful relationship. The author does a great job of capturing Reid's personality. 'Love in the Shadows' is also worth reading. It has a bit of mystery in it as the relationship between the two unfolds while they are dealing with a case together.
Another good one is 'Shared Secrets'. This fanfiction focuses on the idea of the reader and Spencer sharing secrets that no one else knows. It delves deep into their emotional connection and how they support each other through difficult times. The way the writer portrays their relationship growth is very believable.
I'm not sure of specific Eliot Spencer hurt fanfictions off the top of my head. You could try searching on fanfiction websites like Archive of Our Own. They have a large collection of fanfictions and you can use the search function to look for ones related to Eliot Spencer with the 'hurt' tag.
There's also the 'co - workers to lovers' trope, especially considering Spencer's work environment. They start as colleagues, sharing cases and experiences, and then their relationship evolves into something more romantic. This trope allows for a lot of professional and personal interactions to be explored.
One common theme is mystery. Since Spencer is from Pretty Little Liars which is full of mystery, many fanfictions incorporate that element. The reader often gets involved in solving the mysteries alongside Spencer.
