Flatpaks and Snaps are supposed to replace native distro packaging, in order to be distro agnostic (you could run it on any distro), the issue with Snaps is that it depends on Canonical’s mood and it is Ubuntu “native”, whereas Flatpak is way more used elsewhere.
There is AppImages as well, but it used to a lesser extent.
I am not sure if your usecase can be fulfilled with
dristrobox
, it may be worth to try
