Unfortunately, as a solo developer on macOS, some of the more complicated approaches don't seem feasible from a maintenance and support standpoint—at least not initially. I hope to stick with the macOS App Store as well, which I assume adds additional complexity since that type of offering is not supported natively by the framework (to my knowledge anyway).

I would like to explore additional options in the future, but I don't see any major overhauls happening in year 1.
