If you’re asking to use macOS with your fingers, you have not realized how terrible that would be. I do not mean in a desktop-OS is terrible for touch input. I mean in a macOS specifically is not built for fingers and would require so much work that Windows has been doing for a decade at this point.
It's not like Windows 10 is touch ready in any real sense, either. Windows 11 fixes some of the basic problems, but the gold standard for a desktop OS that's productively usable in tablet-only mode might ironically be GNOME on Linux.
What I do right now is typing with the keyboard and extensive use of the GUI with my fingers. So I'd still want at least a detachable keyboard, but also use it in full tablet mode. Among its uses, I'd read sheet music from it at band practice.
