Basically, I just followed this tutorial for my EndeavourOS installations. It’s as easy as choosing an older entry in GRUB. Fedora offers something similar by default, and I think Tumbleweed does too.

Moreover I’m now playing with Arkane Linux (https://arkanelinux.org/), immutable flavour of Arch, it features another magic with btrfs and rollbacks without snapshots and GRUB

I use Btrfs for my root partition to be able to rollback if something goes wrong after update. XFS: in all other cases, since I hate the lost+found directory on ext4. Although I don’t think there’s any significant difference between ext4 and xfs in performance and reliability.
