All I really used with basic org-mode was the labelling stuff. I could press a key and cycle between todo/done/whatever.
Really worked well with my list of lists mentality :) that was mostly thanks to org-agenda.
To tell a lie: I also used org-mode to write my emacs config, through literate programming. I don't have it any more, but it's a common thing to try. org-babel will compile your literate codes in sequence, throughout a document.
Thing that turned me off was that I work in WSL2 on Windows and my emacs setup there is for programming, and I didn't want to get into that context for this other stuff. Which means, making a second emacs config. Maybe I'll do it sometime, but right now I'm just figuring out what I'm asking for.
