From this answer and the discussion in comments:
[T]he problem is mechanical damage: every time someone picks up a
piece of fruit and puts it down again it may cause small soft spots
and local damage – And think about the shoppers that try to judge
ripeness by pushing or pinching the produce. This will cause damage,
invisible at first, but rotting soon, either in the store or at other
unsuspecting customers’ homes – Stephie
I had considered the harms of pushing or pinching the produce before this, and tried to avoid doing either, but hadn't thought of the damage from simply picking up something and putting it back down. And now that I think of it, I can't come up with a way to examine fruit without causing such mechanical damage. Even rolling it around in-place could be just as, or more, harmful.
What can I do to examine fruit without causing avoidable damage?
