I've never seen a way to organize files that feels like it prioritizes files based on how much they mean to the user.
By that I mean pictures I take, papers I write, things I really wouldn't want to lose, vs 10,000 random system files.
For downloaded files sometimes the history of when it was downloaded, and from where, is almost as important as the contents.
Backups from old computers, and old phones start to pile up, and the chaos of trying to find that picture you took 3 phones ago, or the notes you took, or the recording you made, or the pdf you downloaded, or that code you wrote, or that map you made, is a real pain.
Digital clutter is one of my biggest problems.
I really need a good way to deduplicate and organize ALL my digital stuff. Tags might play a role, but I don't think they quite solve the problem.
