I'd recommend you do your best to stay away from rigid category-like classifications and see what develops. For specifics see: https://boffosocko.com/2023/01/19/on-the-interdisciplinarity-of-zettelkasten-card-numbering-topical-headings-and-indices/
If it's easier to conceptualize, think of it all like a map which may have place names, but also has numerical coordinates. Sometimes a specific name like Richard Macksey's house is useful, but other times thinking about a specific coordinate and the general neighborhoods around them will be far more useful in your community development plan. A religion-only neighborhood without religious activities, religious food, religious organization or communication will be a a sad one indeed. If you segregate your communities, they're likely not to be very happy places for co-mingling of ideas and the potential resultant creativity you'll get out of them.
Bob Doto also suggests a similar philosophy in some of his work, particularly with respect to folgezettel: https://writing.bobdoto.computer/zettelkasten/
I'll note that this is an incredibly hard thing to do at the start, but it's one which you may very well wish you had done from the beginning.
