My ex sorted all my documents for me, and the system works pretty well! It's an Ikea storage box (~14"x14"? they have a million of em), and she added these green file folder separators with little metal tabs on the ends, that hang on the edges of the box. Manila folders sit cradled inside the green separators. The manila folders have tabs for a label on top, and I'll put a category and year on the label. All I have to do is take out the box and all the labels are on top, so I can very quickly just see "Taxes" folders and look for the "Taxes 2019" folder. When I move again I may digitize them by setting up a 'jig' using a piece of acrylic or glass from Home depot to flatten the pages so I can photograph them. Once that's done, I just keep a folder on my computer called "Documents" that gets copied to the cloud or wherever. Same basic filing system as the paper documents. One copy in the cloud and one on my computer, and every few years I make some kind of offline backup that I then forget about for years.
