This is really interesting, both as a topic and as just general history geek stuff. Have you considered the intolerance hypothesis for the spread of christianity (and islam after it)? I vaguely remember reading about it while in undergrad and it essentially says that christianity managed to dominate because it was exclusive, meaning required you only believe in the christian god, unlike other roman pagan religions.

I vaguely remember the last pagan generation being a good source on early christendom as well: https://www.amazon.co.uk/Final-Generation-Transformation-Classical-Heritage/dp/0520283708
