Several of the YouTube reviews of the R7 have shown that the AF area is proportionately bigger on the crop sensor when using the RF 600 & 800 f11 lenses.

Isn't that also what I'm writing for the R7/R10 vs. R5/R6? (You might be answering an earlier version of my post before I edited it)

But how does one explain the 80% x 80% coverage on the EOS R3. Some other factor than sensor size must be involved too (in general)?

It is not the sensor size per se but the individual sensor design that matter. The R3 uses a stacked CMOS image sensor design using a radically different technology than the R5 or R6.
