I am not sure we agree on what "advanced morals and ethics" would mean, but the Hugo award winners are generally good ones to explore for discussion of ethics.
Foundation series is a famous one that comes to mind, but plenty of other examples in that set. Enjoy!
Thanks so much! Loved the first two Foundation books, but did not find the humans really any more morally or ethically advanced than us today. What I must dug about the stories was the vast sense of scale they shared, and allowing things to happen naturally at the right time and place.
