One common theme is sacrifice. They often sacrifice for each other in these fanfics, like Castiel giving up his grace or Dean putting himself in danger to save Castiel. Another is the exploration of their unspoken feelings. Since they don't always express their emotions openly in the show, fanfics love to dig into that.
Well, a major theme is the power of their bond. It's often shown as something that can overcome all kinds of supernatural threats. Also, redemption is a theme. For example, Dean might find redemption through his relationship with Castiel, or vice versa. And of course, love in the face of the apocalypse or other dark forces is very common. These fanfics show how their love can be a light in the darkness.
The themes usually revolve around their deep connection. This can be in the form of a soulmate - like bond. Many fanfics also deal with the theme of trust. Given the dangerous world they live in, their trust in each other is crucial and is often explored. And then there's the theme of self - discovery. Through their relationship, both Castiel and Dean often discover new aspects of themselves that they didn't know before.
