I'm looking for a way to have my phone automatically switch to vibrate or silent when the screen is on (and switch back when it goes off) since it's pointless and kind of annoying for it ring when I'm already looking at it. I feel like I've had Android phones that did this before but I'm not sure. I have a pixel 3 running 12 if that matters.

You might need an app such as If This Then That or Tasker to do this. I've had Android phones going all the way back to the Moto Droid (the one with the physical keyboard that slid out) and I don't recall this functionality.
