I have watchtower configured to update most, but not all containers.
It runs after the nightly backup of everything runs, so if something explodes, I've got a backup that's recent and revertible. I also don't update certain types of containers (databases, critical infrastructure, etc.) automatically so that the blast radius of a bad update when I'm not there doing it is limited.
In the last ~3 years I've had exactly zero instances of 'oops shit's fucked!', but I also don't run anything that's in a massive state of flux and constantly having breaking changes (see: immich).
