Yes, software that is in a package manager is similarly easy on a Mac. There's an app store, which can be used to install the dependencies for homebrew (which is a good package manager for most of the stuff that Linux package managers maintain, including building stuff from source). Going outside of a package manager is relatively easy (but needs to be enabled, as the defaults basically discourage users from installing software not verified by Apple), but that method of software installation still beats running .exe/.msi installers downloaded from the internet, beats running random shell scripts, probably beats downloading docker containers and flatpaks, and is not that far removed from installing from the AUR or something like pip/conda: you still need to know what you're doing, and you have to trust the source/maintainer. None of that is unique to any operating system, except those that simply don't allow you to install software not reviewed/approved by the manufacturer (Apple mobile devices, Android devices by default).
