The Culture novels postulate a form of luxury space communism for humans, but the plots involve other things. It's not exactly wish-fulfillment; luxury space communism is hardly all good. It seems to me that most post-scarcity futures imply some kind of luxury communism, and if you're writing space operas, they'll necessarily have a mild or extreme form of luxury space communism. You could segregate the haves and have-nots, but then you get something like Elysium (the movie) where the obvious plot involves the have-nots revolting.
I guess I don't understand what you're looking for. You don't want the author to project their worldview, but you do want them to try to predict the future, not too optimistically, but also not too pessimistically? A scifi sitcom, where nothing of note happens that's overly positive or negative? Wouldn't that be projecting the author's worldview too? "Maybe life in the future is going to be just like today"?
If you just don't like scifi in general, or space operas in particular, that's allowed.
Cyberpunk is fairly dystopian, and not really a projection of how the author wishes the future to be, so it's curious that you cite Gibson who wrote proto-cyberpunk, before writers like Morgan and his Kovacs series. Have you looked into those?
KSR's Mars trilogy maybe?
