Well, it could start with the elaborate preparations. Mal might be nervous about becoming queen and Ben's wife. There could be some drama from the VKs who are worried about how things will change. And of course, the wedding ceremony could be a grand affair with all the characters from Auradon and the Isle in attendance. Fairy Godmother could be in charge of the magical elements, like making sure the weather is perfect and the venue is beautifully decorated.
One popular fanfiction might be 'Mal and Ben's Royal Wedding' which details their big day with lots of fairy - tale elements. It describes the grandeur of the ceremony, Mal's beautiful wedding dress, and how all their friends from Auradon and the Isle come together to celebrate.
One great Mal and Ben fanfiction could be about their adventures after the events of Descendants 2. Maybe they go on a secret mission to another isle to help some lost souls. It could be filled with magic and their growing relationship.
Often, a plot point could be the inclusion of characters from both Mal's and Ben's worlds who might not initially get along but come together for the wedding. For example, some of Mal's friends from the Isle might be a bit rough around the edges compared to Ben's Auradon friends.
Obviously Mal and Ben are the main ones. But Evie would be great as Mal's maid of honor. She could help Mal with her dress and give her lots of advice. Carlos would also be there, maybe in charge of some of the tech aspects like the lighting or sound. Jay could be the one to make sure all the guests are seated properly. And from the Isle side, Uma and Harry could add some interesting drama and then end up being part of the celebration.
The wedding ceremony would be a sight to behold. Since Mal is from the Isle of the Lost, there could be elements of the dark and mysterious in the ceremony. Maybe the rings are presented on a floating skull - shaped platter. The officiant could be someone like Fairy Godmother, who has seen the growth of both Ben and Mal. The guests would be seated on benches made of enchanted wood, and as they say their 'I dos', a gentle rain of glitter and petals would fall, signifying the new beginning of their united rule.
One idea for a fanfiction could be about how Mal and Ben's baby selves might interact in a magical nursery. Maybe there are enchanted toys that reflect their future selves. For example, Mal's toy dragon could be a sign of her future connection to Maleficent's powers.

The plot might involve Ben and Mal teasing a new student from the Isle of the Lost.
