I did this for a while but I never ended up carrying both phones - if I’m at home anyway, might as well use a laptop (or a TailsOS usb on a keychain if using someone else’s computer).
If you want privacy at all, I think it’s best to accept the trade-offs and use CalyxOS. You can create a sandboxed work profile for Google Maps, Pay, etc and turn it on if you get in a jam. And maybe just carry a little cash. I didn’t need NFC payments a couple years ago, and I don’t really need them now.
Enjoy the new Pixel! (And update it, because the Samsung Chips have a zero-day exploit). 🤙
