I would highly recommend 'Reid's Redemption'. This fanfiction shows a different side of Reid as he tries to overcome some personal issues while also developing a relationship with the reader. The way the author writes Reid's character is very true to the original show. Another good pick is 'In His Arms'. It has a very sweet and tender portrayal of the relationship between the two, with some really touching moments that will make you fall in love with the story.
There are quite a few amazing Spencer Reid x Reader fanfictions. 'A Chance Encounter' is a really nice one.

'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.
Love is a very common theme. It could be a romantic love between Reid and the reader, showing how they overcome differences and build a relationship. Another theme is friendship. Since Reid is part of a team, stories often explore his friendships within the team and how the reader fits into that dynamic.
One of the most popular themes is solving mysteries together. Since Reid is a genius profiler, having the reader character be involved in the crime - solving process creates an exciting dynamic.
Love and acceptance are also common themes. Since Reid is a bit of an outsider in the show, fanfics might show how the reader character accepts him completely and they fall in love. There's also the theme of Reid's past traumas and how the reader helps him heal. For example, in some fanfics, the reader is there for Reid when he has nightmares about his mother's illness.
One great 'Spencer Reid x Reader Fanfic' is 'The Unspoken Bond'. It beautifully portrays the relationship between Spencer and the reader with a lot of emotional depth. Another is 'A Helping Hand' which focuses on Spencer using his intelligence to protect the reader in a dangerous situation. And 'Love in the Little Things' shows their relationship growing through small, everyday interactions.
One popular trope is the 'genius and the normal'. Since Spencer Reid is a brilliant genius, it's common to see stories where the reader is an 'ordinary' person who is drawn to his intelligence. Another is the 'hurt/comfort' trope. Reid has been through a lot in the show, so fanfictions often have the reader comforting him. For example, after a tough case.

A good 'Spencer Reid x Reader Fanfic' should have a strong character development for both Spencer and the reader. The relationship should feel natural and not forced. For example, if the writer shows how the reader's personality complements Spencer's quirks, like his fast - talking when he's excited and how the reader patiently listens. Also, a well - written plot that ties in with the 'Criminal Minds' universe is great.
Once, the reader was a new agent at the BAU. Spencer Reid was immediately intrigued by the reader's unique perspective on cases. They often worked together late into the night, sharing coffee and theories. One day, during a particularly tough case, the reader got injured slightly. Spencer was beside himself with worry. He stayed by the reader's side in the hospital, and that's when they realized their feelings for each other had grown into love.
