most apps on linux run unconfined (as much as the kernel/apparmor/selinux/firewall allows), but linux app stores have been developed for this purpose (and for compatibility between different types of linux). flatpaks and flathub.org is probably the one that's closest to what you're looking for like this anon points >>105643689

with this you can have confined applications with permissions, and installing flatseal you can have a gui for managing permissions for each app installed this way. does come with compromises like some apps not interacting that well with each other but that can be a feature depending on the app.
