I empathize with you. I really do. All I can tell you is no matter what's written, no one, not Apple, not Samsung, not Google, has found a glass which can't scratch. I do appreciate the new phone's glass is harder to break. My partner has a tendency to drop his phone. Cases can help a lot, but the impact with phones of just a few years ago, and one could be spending a lot of money to replace the screen. Another advantage to screen protectors is they often take the impact of a fall and they break, but the phone won't. This happened with his iPhone 11. The screen protector shattered. The iPhone screen was perfect. We just used the lifetime warranty on the Belkin protector and had it replaced for free.
I don't even read the fancy words about the glass. I already had a couple cases before the phone arrived and before I even powered it on, I had Apple install the Belkin Screen Protector with the magic Belkin Screen Install Machine. Then I turned the phone and went about setting it up.
Edit: There's a guy on YouTube called Jerry Rigs Everything who every year tests the scratchability of every new iPhone. iPhone 11 scratches on the Mohs Scale at level 6. Keys, coins, etc, won't scratch the screen. iPhone 12 is actually harder at closer to Mohs 7. But the biggest culprit is micro granules of sand which is predominantly quartz. People put their phones in their stone washed jeans and there are bound to be residual micro grains of quartz in their pockets. I'm not saying you've put your phone in stone washed jeans, but sand is everywhere and since sand is higher than Mohs 7, it scratches phones unfortunately.
