Becky Chambers is probably the single best young author working in this genre today. She's got two great series, one that begins with "A Psalm for the Wild-Built", and one which begins with "The Long Way to a Small Angry Planet".
I'd argue Andy Weir's "Project Hail Mary" is hopeful sci-fi, and the movie adaptation was great. You could perhaps put Adrian Tchaikovsky's "Elder Race" and "Service Model" in there too, since both are pretty hopeful in overall outlook. And if you broaden to include fantasy, Travis Baldree's "Legend and Lattes" series is very much in the same vein as Becky Chambers.
It seems like hopeful sci-fi movies and TV are more common, like the recent "Star Trek: Strange New Worlds".
Perhaps the recent troubles the world is undergoing will lead to more light-hearted fare to distract us? One can only hope.
Ada Palmer's terra ignota. It takes 'the past is another country' and really sends it forward. The world she draws is fundamentally different from our own, as ours is from medieval France. Absolutely fascinating books, with their own set of Utopians trying to make a better world for the future...
And I'm the vibey solar punk direction, Becky Chambers' 'Monk and Robot' is a fascinating pair of novellas about humanity reestablish ing contact with robots after they decided to just leave 250ish years previously. It is very much a book about a Good Future, where people still have people sized problems.
It should be ignored by savvy readers, and abolished from the writer's vocabulary.
We've been on this pathway since the Lisbon Earthquake of 1755.
What an intriguing thing to say :)

The pathways are all there in search. You won't need AI to find them. It's often mentioned in histories of philosophy from Lebnitz onward, he was the last great religious optimist in some ways. Not that there aren't any, but they don't exactly come to mind the way Kant, Voltaire & Rousseau do.
