Next set of examples is uploaded. I've double-checked that these are all Single-Area AF (rather than Dynamic Area AF, like the first two).
JosephK: I'd appreciate if you could do the overlays again, at least for one or two of the images, just to confirm that the camera and I are on the same page about focus points.

Note that this is clearly happening on two cameras. 701_ prefix is one body, 710_ prefix is a second body. I bought the cameras in a single order, though, so if there were something amiss with their batch, it's possible that they're both affected.

Finally, I've drawn the red dot at the exact center of the image. Given that (I thought) I was using the center focus point, I would expect the red dot area to be in focus. Instead, the camera has clearly decided it'd rather focus on the background.

Images are here, sorted by upload time. Farther down is newer:
