No discussion of Workflowy (https://workflowy.com/)? It is, in my opinion, by far the best note-taking app I have used. You can search, reorganize, and freely move content as you take it, and also after. You can nest a whole campaign of D&D notes next to your favorite recipes, and it feels natural due to their focus level model. More importantly, it's absolutely dead simple, and it "gets out of the way."

The author dances around the two main properties that all good note-taking methods have:

1. It's easy to add new notes 2. It's easy to look through old notes to find what you want

Pencil and paper, or bound journals, do the former very easily. The latter is much harder, unless you start some indexing system (such as a bullet journal solution). This suggests searching and tagging are ideal, which digital is good for. But, and I cannot stress this enough, (1) is more important than (2). It is not impossible to find information in hand-written notes, just harder. But the exact moment it becomes hard to take new notes, the solution fails because you won't use it. And I believe Workflowy does all of this, with quick nesting, easy extension, and even quick reorganization. And you can quickly drop into "just let me write some notes," then go back and organize later (even splitting your notes up into subcomponents, if you want).
