For my research (humanities) I self-host linkding to keep track of web stuff and use tmsu to tag all my local files (pdfs, images, etc). I also use zotero for biblatex/word processor integration. I admit it gets a little clunky working across those systems, but the key for me is keeping the tags consistent across all of them. I guess I'd be interested in an all-in-one solution, but I'm years deep into this setup, so I can't imagine the effort it would take to transfer everything over.
