Worth noting that even if you’re installing from the web installer you may still need the google USB driver as described in the manual installer. My test install (on pixel 8) kept stopping at the fastbootd screen until I installed the driver on my laptop. Took me a hot minute to work out what was going on.

Seconded.

I have calyx os running on my pixel 4 as my daily driver, with microG so I can still use banking app and M$ apps I need for work.

As you can unlock and relock the bootloader, the device security will still attest to the OS validity so security sensitive apps will still work. You can also put the stock Google OS back on easily at a later date if you so choose.
