In terms of Effective Altruist Fiction, I think Unsong ( http://unsongbook.com ) is a great example. Despite the premise being rather strange (The Bible and Talmud are literally true), Peter Singer and EA get explicitly mentioned in Cantors and Singers, and the Comet King is a great example of a utilitarian protagonist who genuinely tries to do as much good as possible (by trying to literally destroy Hell).

The idea of communicating Long-termism through fiction is discussed in an episode of the 80000 hours podcast ( https://80000hours.org/podcast/episodes/aj-jacobs-on-writing-reframing-problems-as-puzzles/), although Rob suggests an Office-style sitcom, whereas I think a science fiction thriller would be more interesting and potentially more effective.
