An UPS won't help though unless you program your Mac to check the UPS status and flush accordingly.

I'm not entirely sure how a UPS works with a computer, nor exactly how this flushing works, but doesn't a UPS run for awhile in the event of a power disruption, certainly more than the several seconds delay with this flushing?

That’s been built in to macOS since the 2000s - there’s a standard USB protocol which most UPS vendors support.
