The Culture series by Iain Banks. It's level of post scarcity makes Star Trek look destitute.

The Culture series by Iain M Banks has an interesting spin on a utopian society.

None of these are Utopian but a trend towards being better.

One of Ted Chiang’s short stories The Story of your Life (the basis for the movie Arrival) perhaps?

Might I suggest Walkaway by Cory Doctorow, my favorite book. The structure is like a Kim Stanley Robinson novel where there's a group of characters but the real character is the birth of a post scarcity society, namely the one in Down and Out in the Magic Kingdom.

I loved it because it answered the problem I had with anarchism: what happens when a psychopath decides to take your shit? The answer is--in a post scarcity society--you walk away. You can always make new shit, better shit, grander shit.

I don't want to get into spoilers, but there was one thing that always was bugging me about this premise. Like, what if X situation happens? Wouldn't you know it, X situation happens. He interrogates the premise to its logical conclusion.

I would kill to see this novel made into a decent TV series.

I found Beacon 23 by Hugh Howey to be a little too optimistic to be realistic in the end. I don't mean that in a bad way, as I thoroughly enjoyed the story, including the ending. I'm just too much of a pessimist. :-)

The solarpunk genre in general might have some good stuff for you - my favorite so far is Murder in the Tool Library, but the Terraformers might be closer to what you're looking for.
