When you are familiar with something and how it works, everything seems easy. When you are unfamiliar with it- everything seems to be written in Greek. Unless you're Greek. Then it is written in Portuguese.
The Software store most closely resembles Windows Store, so it is included in Zorin OS.
The Software store is made by Canonical - the company that distributes Ubuntu.
Canonical developed Snap Packages; and took some liberties when they made the process. This caused users to reject Snap. Canonical responded promising that Snap would never replace APT (Debians Advanced Package Manager).
Then, they broke that promise and replaced APT with Snap. The Software store will sneakily install Snap Packages, instead of debian from APT packages.
ZorinGroup modified the Software Store to account for this, providing easy access to checking the source in Software. You can find this on the Headerbar of the Software Store on the right side; when you have any application selected in the store. This way, you can check and know right away if the source is the Ubuntu Main repository (debian packages through APT) or if it is a Snap Package.
When I first migrated from Windows to Linux (on Zorin OS), I struggled with installations a lot. It took some learning. But things really came together when I stopped resisting the terminal and began using it for installations.
It makes installing so much easier. You do one line:
sudo apt update && sudo apt install (Package-Name)
Done.
Coming Soon.
ZorinGroup is working on an ARM version of Zorin OS.

There are pictures around the forum somewhere of that...
