Another user of paperless-ng here. For a while, I used another open-source alternative Mayan EDMS - https://www.mayan-edms.com/.

As opposed to paperless, Mayan provides fine grained access control via ACLs and also allows 'directories' in addition to tags. Dropped it after a while though, since it was too enterprise-y and for in-depth configuration, the documentation was insufficient and I would have to buy the advertised book. Paperless-ng is sufficient for my personal use, though I still miss having directories as an additional level of hierarchical organization alongside tags.

Since I don't have a scanner, I just use the Microsoft Lens app to scan documents on my phone (Android). Paired with Syncthing (https://syncthing.net/), my documents are automatically synced to my desktop from where paperless-ng picks it up from the watched folder and automatically adds it. Tags and correspondents can be automatically added based on keywords in the text.
