I am currently using Linux Mint (after a long stint of using MX Linux) after learning it handles Nvidia graphics cards flawlessly, which I am grateful for. Whatever grief I have given Ubuntu in the past, I take it back because when they make something work, it is solid.
Anyways, like most distros these days, Flatpaks show up alongside native packages in the package manager / app store. I used to have a bias towards getting the natively packed version, but these days, I am choosing Flatpaks, precisely because I know they will be the latest version.
This includes Blender, Cura, Prusaslicer, and just now QBittorrent. I know this is probably dumb, but I choose the version based on which has the nicer icon.
Flatseal is super easy for anyone with a tech background to use. You can very quickly expand or reduce the access an app has to your system. Even below what the app comes with by default.
I do kinda wish the guis for installing flatpak apps were more forthcoming with the permissions, and possibly integrated some of the features of flatseal so you could modify the permission set before installing.
It does seem pretty intuitive.
Honestly I just sometimes want the app to see a file outside of Downloads.
