I figured it would come down to antennas.... but I am still disappointed...

AM/FM is really up to the handset manufacturer, some phones have the hardware turned off by the manufacturer.

A number of phones, including my Samsung Galaxy S10e, have the built-in FM radio enabled. It needs to have a earphone plugged in, which it uses as the antenna. The app is NextRadio.

I had a very cheap Android phone for a while that had this. Unfortunately, later flagship phones I got seemingly did not.
