On the Avoid-Them characters... Is there a way to pull these off well? Make them antagonists?
Absolutely. I didn’t mean you shouldn’t write those archetypes at all, I just meant that, in my opinion, you should refrain from glorifying them the way a lot of modern media does (particularly in the case of the male protagonists.)
You can write abusive partners, for instance, just don’t present their behavior as noble or romantic.
You can write entitled “nice guys,” but don’t present them as correct in their assumption that the women they desire are owed to them.
You can write autistic characters with neuroses and quirks, but put in an effort to depict them with authenticity, accuracy, and respect instead of making them a conglomeration of blaring stereotypes.
And you can write abusive parents, but make sure the narrative makes it clear that their behavior was wrong and nothing will justify it.
And so forth. I’d also like to make it clear that you don’t have to take my advice, as my opinion is, by nature, subjective. But in any case, I hope this helps!
Best of luck, and happy writing. <3
