Hard to imagine any way front or back focus can happen with mirrorless, especially since the problem in DSLRs is a mechanical one.

My experience with a m6ii is that landscapes always present focus problems since the photo is cluttered and even the spot on mirrorless is huge compared to my former 70D which had a much smaller spot focus point.

But if I understand correctly, these are focus problems that are more likely related to an incorrect focus point selection by the camera, right? Or have you also noticed this in situations where the AF point was on an unambiguous part of the image?

I've only noticed something in cluttered scenes.

I tend to use touch screen focus most of the time. You may want to try that?

I mostly shoot using the viewfinder and I use Touch&Drag AF if needed (see below).

Also, Canon's Digital Photo Professional will show focus points. You should check with the software. It should also tell you if focus did not lock.

A few days ago, I installed DPP for this purpose and I found that I did in fact set nonsense focus points from time to time - probably unintentionally with my nose since I had "Touch & Drag AF" active on the whole panel. Now I switched that to "Bottom right corner", which works fine and avoids setting random focus points

Anyway, in most of the too-soft pictures, the AF point was placed as intended. But the results are still puzzling, not at least because most of those pictures weren't shot to check some AF problems. I guess I will have to do some more structured testing to narrow down the source of the error.
