Furthermore, when it was done, the settings were all wrong and you cut way too much. They all sound muffled and over-processed.
Cutting 12 dB from broadband noise and at least 12 dB from the hum is the test condition. If you can do it better with these tools - why don't you post the result? Using noise reduction for "cyclical" noises is not a "brute" force, it's one of intended uses of noise reduction. This is emphasized in the manual of TC BackDrop or iZotope RX, for example. So, you are just not familiar with this use.

Of course not. I've been using a set of notch filters, available in DeHum modules of many software.

I really know different tools
One of my goals has been to demonstrate that broadband noise reduction can succeed on tonal noises where notch filtering fails. Notch filtering mostly fails on this sample.
