Pixel phones are arguably the worst for rooting. (I own one) In order to get the phone to pass properly you pretty much have to go custom on the ROM.
I’m running a stock firmware, and I get all sorts of problems as a result of rooting the device, and not installing a CFW.
I have 2 apps, that won’t work (google pay and a credit score check/lock appand Microsoft intune - which my work partially uses)
Edit and did I mention? The LSPosed zygisk module causes so much instability I can’t use it.
