All software and by extension OS are text oriented regardless of appearance. If you take a wad of human readable text and use it to built a binary blob then the blob is a function of the original program text ergo the text is still there just liable to be inscrutable. Classic Mac OS hot garbage. They switched because unix was a better basis for an OS than anything that could possibly have done with their existing OS short of throwing the hard drive containing it out the window and starting over. You can install a user oriented distribution like Mint or Ubuntu and never see a cli if you don't want to. So far as I can tell the gui tools that come with these distros are complete for all standard tasks. Minimal or technical distributions like arch, void, gentoo are pretty obviously meant to managed with the cli although users can still use rich gui tools for many non system tasks. Few are wallpaper over cli tools. I don't know where you got that idea.
