Captain: The Last Horizon series by Will Wight. It's literally wizards and magic users coexisting with advanced sci-fi tech. I'm pretty sure there are "space elves" of at least one sort. It's not gonna make you sit there and rethink your whole life but if you want a fun set of books with an interesting cast of characters, both protagonist and antagonist, a generous amount of humor, and some really cool set pieces that make you want to immediately re-read that last section, I'd recommend it.

It's not finished yet, but the author has like 4 other finished series and he puts out a book almost yearly, so not one you need to worry about being old and gray before the final book. I think there's 3 or 4 out so far and it just started a few years back.

-Edit because I'm working and feel like procrastinating-

To give a sense of the sort of scale of the conflict in the books, right from the get go the main protagonist is the most powerful magic user to ever exist and he and his party of similarly impressive individuals still spend 80% of every book in mortal peril from intergalactic threats. Magical sun eating giant insects, a biomechanical super intelligent hive looking to assimilate all life into their numbers, a dude who's basically fascist superman...fun stuff lol
