I would suggest using ‘apt-get dist-upgrade’, if upgrading manually,
because:

(1) ‘apt upgrade’ will currently never remove a package, even if that’s
    necessary to upgrade something else.

(2) ‘apt’ is permitted to meaning from version to version, so any advice
    given about it today could be invalidated tomorrow.

When to upgrade:

* I use https://wiki.debian.org/UnattendedUpgrades, which takes most of
  the hassle out of it.

When to reboot:

* /var/run/reboot-required should be nonempty if you need a reboot.

* https://packages.debian.org/bookworm/needrestart should help with
  reboot notifications.

* unattended-upgrades mentions any need to reboot in its email
  notifications.
