It really gives a warm and fuzzy feeling about their married life.
Another plot could revolve around the challenges of raising a baby in their dangerous world. They have to constantly protect the baby from their enemies. Maybe there are villains who try to kidnap the baby to get to Oliver or Felicity. So they have to set up a super - secure hideout and enlist the help of their friends like Diggle.
Oliver would likely use his skills from being a vigilante to protect his family. He might set up high - security measures at home. Felicity could use her tech - savvy to monitor the baby while they are out on patrol. They would also have to rely on their friends and allies to help out when they are dealing with threats in the city.

Another could be them planning to start a family and all the joys and concerns that come with it. Or perhaps they take a trip together and encounter some old enemies during their journey.
One common plot idea is exploring their life after the events of the show. For example, how they handle raising a family while still being involved in the vigilante world. Another idea could be alternate universes where they meet under different circumstances, like Felicity being a superhero herself and Oliver being a tech genius who helps her.
There might be a fanfiction where they time travel to the future. In this story, they could see the consequences of their current actions and have to figure out how to change things in the present to avoid a dark future for Star City. They might encounter future versions of themselves or their friends, which would add an interesting dynamic to the story.
A lot of fanfictions also focus on their relationship development. This could include how they deal with challenges in their relationship, like jealousy, misunderstandings, or external threats. Some stories might explore their pasts more deeply, revealing secrets that they haven't shared in the original show, which then impacts their present relationship.
