Thanks for this excellent summary, I hope giving the example will indeed help to make this topic more accessible.
I'll take your invitation on

seeing that circumstances for 'better noise performance' are not explicitly mentioned, and are still a point of confusion, maybe you could put this way:
"The advantage to the
full frame sensor is that it has one stop of narrow Depth of Field that cannot be taken on APS-C, and only for those narrow Depth of Field exposures, the sensor receives more total light and has a one stop low light performance advantage."
What's missing in your writeup is a discussion of dynamic range. If you assume the same number of pixels, the full frame pixels are bigger and able to hold a larger maximum amount of charge, while maintaining a similar, but not equal, low-charge noise floor in combination with good amplifiers/AD converters. Thus the dynamic range that the sensor can capture increases. As can be seen in measurements, this is not always a full stop, but noticeable.
