One great fanfiction in this theme might be 'The New Beginning' where it beautifully depicts their journey into impending parenthood. It shows how Meliodas is both excited and a bit nervous, and Elizabeth is full of anticipation.
There's a fanfic called 'Melizabeth's Miracle' which delves deep into how their friends react to the news of Elizabeth being pregnant. It's really interesting as it shows different sides of the characters we know and love from the series, like how Ban tries to give parenting advice based on his own wild experiences.
One plot idea could be that they face challenges from outside forces who are either jealous or see their unborn child as a threat. Maybe an old enemy tries to target Elizabeth during her pregnancy, and Meliodas has to go to great lengths to protect her and their future family.
Another plot twist might be related to Elizabeth's memories. Since she has had multiple reincarnations, there could be something in her past memories that affects the pregnancy. For example, a past life's vow or curse that she was unaware of starts to have an impact on her current state of being pregnant.
There could be some stress on their relationship too. The responsibilities of impending parenthood might cause some arguments. For instance, they might disagree on where to raise the child or how to handle the child's potential powers. But these conflicts would ultimately strengthen their bond as they work through them together, learning more about each other in the process.
One common theme is the anticipation and excitement of becoming parents. This can include scenes of them preparing a nursery or choosing baby names.
