Apologies, I’m not sure what reply you are looking for, so here’s my personal response:
maybe the lack of wider knowledge of “pagan” faiths is that they tend to be much more localized?
example: I know probably more than any person in 100 mile radius about Slavic and Ugro-Finnic old faith, but that’s only because I have personal connection to them, and their elements are pervasive in my cultural foundation? So I want to learn more about those, but not so much about, let’s say, animistic religion of Horn of Africa tribes?
Anyways, whatever religion, as long as it works for you, answers the questions that you need answered, and makes you a better person (now there’s a loaded concept), nothing wrong with that!
