I highly recommend anything by Becky Chambers. Her Monk and Robot series is the definition of cozy fiction and the space series is also very low stakes, but engaging. I would also recommend the fantasy books, Legends and Lattés, about an orc who stops adventuring to open a coffee shop, and the prequel, Bookshops and Bonedust, which should actually be read after Legends.

As Mastema said, Becky Chambers. Her Wayfarers series (first book being A Long Way To A Small, Angry Planet) is sublime. I can't recommend it enough

Midshipman's Hope. It' s Hornblower in space.

Also, Startide Rising by David Brin is "Uplifting". It's about the first interstellar starship captained by a dolphin, with a dolphin and human crew.

They make a momentous discovery which puts them on the run from formidable alien fleets with the fate of all Earthlings hanging in the balance.

I enjoyed Legends and Lattes by Travis Baldtree. It's about a retired adventuring orc who decides to open a coffee shop instead of murdering people

Maybe the book in which the Dune story was created, the Frank Herbert's book.
