Clearly. Too simple a point, apparently.

Sure.

To simplify, imagine a pinhole camera...

Any given field of view thru that focal point contains x lumens.... Those lumens can be 'projected' to a sensor array, or negative, or even a wall. The total amount of light passing is constant thru that field of view, but the lux is not. As the 'projection' behind the lens widens, the lux drops off. So, you can either have intense brightness on a small sensor array, close to the focal point, or a proportionately less brightness on a larger sensor array, which would have to be further from the focal point. (which one is better for low light situations?)

So I am just saying that bigger sensor elements is not a very compelling reason to go to a FF camera. Besides, if you get the FF then you'll just be jonez'n for a medium format 60Megapixel Hasselblad. :-/
