#Joplin works on anything, even a #terminal. Syncs across platforms as well, if needed. The list of everything is at the bottom of the landing page.

It also has a robust message board and I've learned a lot of helpful things there.
Because I like to index a lot of things (in addition to tagging) I appreciate that I could use stuff like HTML to make internally-navigable note collections, as each individual note has its own link available.
Eg: I can organise my research notes easily by both date and alphabetical topic. I could also create a keyword index if I want/need.
Basically, #Joplin is extremely open: YOU decide what to do with it and how you want it to work.
For me, it genuinely revolutionised my life wrt those many bits of paper, whether simply for personal interest or critical data. 
Good luck in your pursuit of the right solution for your needs!
