@britt @Chigaze I enjoy the Wayfarers series by Becky Chambers a lot. I think of it as comfort-sci-fi, but it might be a little too dark for you? Maybe look at a description and see if any of them look interesting. They're only loosely connected so you could read any of them as stand-alones. My fave is #2.
She also has the Monk & Robot Series, which was *too* gentle for me, and I bounced off it as boring/philosophical, but my friends adore it so maybe take a look at those?
