Well you got most of the notable ones in there. We always try to urge users to avoid and minimize the use of clichés, especially the Creeypasta based ones.

A few more I could think at the top of my head. Theory pastas usually involve a person imagination or hallucinating the world they live in, usually because of mental illness (which addresses to your previous point) or coma.

Another one could be the use of inappropriately using historical tragedies as shock factors (9/11, the Holocaust, or any mass killing).

Also making the protagonist overly sensitive (or stupid) to anything disturbing or discomforting.
