I took a look today when I saw this post. The page was updated recently, and the options have changed, and unfortunately reduced. For example, it used to include Noise/Grain. From my brief look, that is missing. That seem to be grouped under Quality and Technical Issues". So from that perspective, it could be agreed upon that with the exception of numbers 1 to 3, of @Nancy OShea list and for MR, "they are all jumbled up under Quality and Technical Issues". As it was before "Technical Issue" was wide, now it is even wider and requires more searching to fine the problem.

The moderation notification options have not changed. The description in the Learn and Support page is a general guideline. If there are multiple reasons for an individual rejection, or if the problem is not covered in a rejection reason specifically listed as an option available to the moderation team, they select the Technical rejection reason.
The best strategy I have found is to look at the rejected file with impartial eyes. It can be hard to do but if you are able to, you will almost always find something.
