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)?

The highest-price body buys you less lens cripple, perhaps?
