Stay away from the loudness tones. Musical tones peaking around 3000Hz, generally written as the equal loudness contours.
You may know it as “baby screaming on a jet.” I fuzzy remember there used to be an Equalizer (or Filter Curve as it’s known now) preset for Loudness, but now I don’t see it.
That and “Essing.” That’s the ice pick in the ear sounds from boosted SS and FF sounds. Audacity has a DeEsser you can install.

The only problem with avoiding those techniques is the competition from people who are using them and the fact that many people are trying to listen on the “wide range speaker system” in their phone. It’s a good way to make your performance vanish.
Good luck.
