As a non-physicist, I found Jeffrey A. Barrett The Conceptual Foundations of Quantum Mechanics, Oxford UP 2019, quite interesting. It focuses on laying out the experimentally confirmed data that basically any theory and interpretation of QM must take into account and "explain" (unless there is something with the experiments or something groundbreaking new is found). It's understandable by laymen. However, at least my experience was that the more I read about QM, the weirder it appeared to me and the harder it was for me to grasp it conceptually.
Feynman : “The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. But nature is not classical, dammit, the imagination of nature is far greater than the imagination of man.”
