Often, there will be some of Captain America's old friends or comrades in these fanfics. For example, Bucky Barnes might make an appearance. He could be like an uncle figure to the son, teaching him about the old days and some combat skills. There could also be new characters created specifically for the fanfic, like a young sidekick for the son who has different powers and a different background, adding more depth and variety to the story.
The Night King could be a great antagonist. His army of the dead and his own powerful magic would pose a huge threat to Captain America. Cap's used to fighting human foes, but the Night King is something entirely different.
