/home got all your desktop environment settings as well as your data.
/etc got all your system settings, including networks available to all users - but restoring this directory on a new host need to be with great care
/var keeps a lot of application/service/runtime system data, as well as logs. Flatpak apps available to all users are also here, but no user data. This directory is great to have a backup of, but only to extract various specific data you realise you really need later on.
/opt and /usr/local are typically the end point for proprietary applications or external third-party software vendors shipping data outside of the ordinary repositories. Normally it makes little sense preserving them, unless you know some of the software uses these areas to save user/runtime data (which is not what these directories are intended for - but third-party vendors are too often ignorant to such advices).

I would also suggest to collect a list of all installed packages (dpkg -l, rpm -qa, etc) as well as all installed Flatpaks/snaps. If you notice you're missing something but can't tell exactly what, such lists can help solve it much quicker.

If you switch distro vendor or there is a larger version jump in the applications/desktop environments in your migration, be careful about $HOME/.config and $HOME/.local. Often it's good to use this as an opportunity to clean up a bit, and just copy over data you see you can reuse. In some cases, some extensions to programs may not work as well on the new host, causing instabilities or sluggishness.
