What are the best works of science fiction that show how the protagonists make a new start for themselves after their quest/adventure/mission is over?

Now we all like to read or watch stories about heroes going on a quest/adventure/mission. Whether it's a soldier or a spy fighting a war, an explorer making new discoveries, an adventurer making rediscoveries, or a mercenary or private investigator catching the bad guy we all enjoy these characters doing what they do whether its kicking butt, saving lives, solving complex problems, and outwitting their enemies.

But after watching Monsieur Slade, it got me thinking. What happens when the heroes are too tired to do any of this anymore? What happens to them when they are spent mentally, physically, or both? Or better yet, once there are no more battles to fight, no more new or old discoveries to make, or no more bad guys to catch what will they do then? How will they be able to move on from their "Life of adventure"?

In any case are there any works of science fiction and fantasy that show the protagonists making a new start for themselves after their quest/adventure/mission is over?

So far the best work I can think of is Star Wars: Bad Batch and the nomad ending in Cyberpunk 2077 (sort of).
