The Complete Robot by Isaac Asimov [2]
The Wrong Unit [3] wasn't a bad little humorous tale.
Pretty much anything by Timothy Zahn (sans Star Wars novelisations) [4] or Robert Sawyer [5] floats my boat.
The First Fifteen Lives of Harry August by Claire North [6]
Barsk: The Elephants’ Graveyard by Lawrence M. Schoen [7] made me care about sentient elephants.
Fuzzy Nation by John Scalzi [8] is very funny. Audiobook version narrated by Wil Wheaton.
Of ones already mentioned:
The Bobiverse was surprisingly good (including the audiobook version).
The Expanse is good.
With regards to Dune, there are some like myself who only ever liked the first book in the series. (Also there is a good audiobook version out there.)
The Long Way to a Small, Angry Planet and sequels are great world building and characters, although the plots seem to meander about with not too much purpose.
The Martian is great.
