`apt` can install everything you can find in the graphical Software Center and more, and with the exact same results (like icons to click on). If it's not available in `apt` repositories there's a pretty good chance you can install it with flatpak, which does roughly the same but is distro-independent. Graphical non-free software like Skype is easy to install with flatpak and "just works" in my experience.
