IME the bootable linux systems are typically read only. Sure you can install anything transiently. Once you connect to the internet, configure the repos, add keys, update the package lists, possibly run an update of the whole system, and idiosyncratic troubleshooting per distro/release/platform. Then you can install something, probably. But, if you reboot, it is all gone and you have to do it all over again. And when it comes to repairing the system there is a lot of rebooting.

I might try it if you are saying the open suse behaves in a different way than the others, but are you?

This one does what you want.  I just installed Wireshark on it and it survives a reboot. https://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-KDE-Live-x8...
