Someone will say it, so it might as well be me: I can't imagine why you'd want such wheels if you're not even racing. Actually, I can't even imagine using them for racing.
With all that said: tubeless.
+1 on the ultra-light rims.
Not worth the risk when descending mountains, especially when not even racing.
I would go tubeless and probably with liners for added safety, but that’s just a personal choice. Tubeless will be more future-proof with tyre choice if that matters to you.
