Still, it’s way better/safer/nicer than searching a program in the internet, download a binary executable from some site you mostly don’t know and running an installer with admin privileges.
You do have to be careful not to subscribe to repos not of your oS version, nor that have conflicting packages - which Yast’s software manager warns you about, anyway.
But yes, standard repos + packman is usually what you need, plus, perhaps:
games
virtualization
google-chrome (or -earth)
libreoffice
That said, I just checked, and there are 25 enabled repos in my main desktop…
