The term RPG is BS to begin with. The broad number of things it has evolved to cover are far from the table-top style games it originated from. Terms like CPRG, JRPG, and WRPG are great for helping us pin labels on things for quick identification, but they have nothing to do with what RPG meant.
JRPGs are generally about stats with a moderately cliché story and are so far divorced from even relative reality as to be laughable. This is plenty clear in most of the over-wrought animations in the FF series.
CRPGs tried to emulate what RPGs were but the technology didn't allow it then and still doesn't truly allow it. Nobody even uses the term really other than people talking about the history of RPGs. These tended to be more hardcore with things like permanent death and specifically not having a map being a feature on purpose. This is as close as it gets and it's history. Nobody wants to play these games any more.
WRPGs just try to focus more on everything that JRPGs don't. They tried to explore settings that the traditional JRPGs don't cover and tend to focus more on character than numbers.
RPGs are the types of games where you can actually play a role. You can make mistakes. You can die... permanently. You can't be 7 different job classes. You are one type of character and play that role. You react in your role to a story that unfolds before you. That doesn't necessarily mean it's only D&D, but procedurally generated content and Turing test AI isn't at the level where you can have these games in any type of reality.
