I've been installing the OS on each new release to a Mac since the 2010s and do a CCC of the filesystem when moving to a new Intel Mac. An OS reinstall on a Mac is pointless if there are no issues. For Linux I keep data on a separate partition so I can mount it via whatever distro I installed elsewhere, then I add the partition to /etc/fstab and mount over /home. Been doing that since 2000s. Windows I only run in a WM or on the work computer so a fresh install for former and the latter is not my problem.
