I do not think that rejecting myth and fantasy precludes a "sense of wonder" or other forms of transcendence. When I dwelt in the fantasy realm of my religion of origin, it produced a faux transcendence, to be sure, but it could not withstand the intrusions of reality, either.

‘Enlightenment’ doesn’t demand anything!

I guess that's a gnostic way of thinking. I like the idea of general enlightenment making the world a better place. I'm sure the gnostics would say that's not possible and history would seem to prove them right but still, maybe some day.
