How Magnus' magic plays a role in their relationship, like protecting Alec or creating special moments for them.
One of the most popular themes is the exploration of their cultural differences. Magnus being a warlock with a long and rich history and Alec being a Shadowhunter from a more traditional background.

Love and acceptance are very common. Given that they are from different worlds (Shadowhunter and warlock), their relationship often involves them learning to accept each other's differences.

Fanfictions often explore how their relationship affects and is affected by their respective families.

Definitely their wedding. It was a huge step for both of them, especially considering the challenges they had faced. It was a celebration of their love in the face of all the odds. Also, the time when Alec stood up to his family and the Shadowhunter society for Magnus was really powerful.
There could be some challenges too. Magnus is used to a certain dynamic with Alec, and now he has to adjust to Alec being more vulnerable. This might cause some minor frictions at first, but ultimately it could strengthen their bond as they learn to navigate this new phase together.

He discovers new things about himself and the new world he's in, which is often a journey of self - growth.
Another theme is the struggle against prejudice. Since they are from different 'worlds' in the story, they face a lot of judgment from others, and fanfictions often deal with how they overcome this. Also, the theme of self - discovery is quite common. Both characters grow and learn more about themselves through their relationship with each other.
Love is a very common theme. Their love story, how they overcame differences to be together. Another is the theme of acceptance, like Alec accepting Magnus' warlock nature and Magnus accepting Alec's Shadowhunter duties. And also the theme of family, as they both have different family backgrounds and how they merge their families in a way.
