When reading non-fiction, I often explicitly aim to read something that will be useful to me (whereas with fiction, I aim for pleasure, with any utility being a bonus).

For that reason, this short-list of some of my recent favorites tends to focus on books that either:

noticeably improved my performance in a tangible skill that has professional value to me (Superforecasting, DOET)
improved a meta-skill that benefits me more generally (Rationality, Talent)
exposed me to a new field resulting in significant learning down-the-line (Enlightenment, Thinking), or
provided pragmatic examples of out-of-the-box thinking that inspired me to think similarly (Feynman, Algorithms)

I'm also a fan of business books from time to time, but find them less useful for me, on average (but still very interesting!)
