Something I think would be useful is a beginner's guide to what you should want your text editor to be capable of. I feel like if you already know what you want to achieve, the main barrier to getting there in Emacs is just getting familiarity with the nomenclature and what packages exist. A good example from this article would be M-q for auto-fill. I was super excited when I discovered that command after spending some time redoing line breaks manually before thinking "I'm sure somebody has solved this problem in Emacs before." I'm sure there are tons of useful text editing hacks that would be really useful that just haven't even occurred to me yet.
