Honestly man, you are overthinking this way too much. YouTube is not a courtroom and the reviewers are not judges. They do not care about your admission of guilt or whether you appealed or not. All they care about is if your channel follows the rules at the exact moment they look at it again.
If you actually have reused content or some shaky videos, appealing is usually a total waste of time because they will just deny it in 24 hours. It is actually better to wait the 90 days. Use that time to delete the trash, fix your descriptions, and upload some high-quality original stuff. When you reapply after 90 days, they just look at the channel as it is then. Not appealing wont hurt your chances at all. Just clean up the house and you will be fine.
