I mean, does it?! Can you tell us what those are, if so?
You listed four games with superficially completely different profiles in virtually every regard that I can think of.
CoC is a mechanically extremely old-fashioned TT RPG with a horror/investigation vibe, which often plays out a lot like one of those investigation board games/experiences rather than an RPG. The players can't really influence the narrative at all, and it's very adventure/story-driven. Low-ish crunch, low rules complexity.
PtbA/FitD is an extremely mechanically modern game that almost works better for people unfamiliar with TT RPGs because it challenges a lot of typical approaches. The players have a huge influence on the narrative, and in many PtbA/FitD games the narrative is driven largely by them too (to the point where they may be making up locations, characters, and so on). Low crunch, low-to-moderate rules complexity.
World of Darkness has various iterations, but is generally a fairly modern design (I mean, it was ahead of its time in the '90s), yet has a fairly classical approach to the player/Storyteller roles. The players may have more influence on the narrative that is typical in D&D, but essentially this is only because of the type of stories being told, rather than because of the mechanical characteristics of the game. Moderate to the low end of high crunch, easily moderate rules complexity, again trending towards the higher end of moderate.
D&D 5E has a retro-modern mechanical design, like it's like the revival of Midcentury furniture and beards, it resembles the past, but in a modern way. The mechanical approach to player/DM narrative control is positively antediluvian, literally nearly identical to the earliest RPGs, just with more positive suggestions ("be a fan of the PCs" etc.). Low end of high crunch, probably the most confused/inconsistent rules-design of any of the games (which is still vastly more together than say, 2E, but perhaps less than 3E or 4E), and the most complex rules, though not by a huge margin over WoD.
To me these are very different games and I don't see any real consistent similarities. Accessibility varies widely, and 5E is arguably the least-accessible of them, yet the most successful.
But am I missing something?
