I agree, cloud version of Revit (and browser access) may be the only way to ever use a non-x86 platform efficiently.
I doubt it would work well, even if a Mac version would existed. If you collaborate/exchange files, Revit is very picky about the exact version used by everyone (i.e. 2024.1.1). Collaborating in a mixed environment (some on Mac, some on PC) would be a total disaster. And you can say about x86 what you want, at least it was consistent and Revit could rely on it being the same. Apple switches forth and back from proprietary, x86, ARM etc. Not worth investing $ in Apple platform since in 2 years they may flip again.
I assume your 2019 Mac still uses Intel/x86? That basically was the same hardware as a windows PC. I have no personal experience, but with the newer ARM M1, M2, M3 any emulation will be even harder/less efficient/impossible since that truly is a different platform from x86 now.
