AFAIK the JDY-40 is completely different to the nrLF24L01.
The JDY-40 is a nice, simple device to use, with an AT command set. The manual is a bit weird though, being rather lacking in detail in some areas. Not unusual for a Chinese device. :)
The JDY-41 builds on the above, including ACK error checking and private connections. However, it's not Hayes compatible. Physically I think it's the same size and pin compatible (but completely different in operation).
The nRF24L01 is a very clever device designed as a network system in its own right. A device can work with a network of up to 6 other nodes, each having its own fully configurable pipe. It's also possible to pass messages through a node, I think, making the network even larger.
TBH the ESP confuses the hell out of me. I can get it to do the very basic things but I've no interest in changing its firmware. That way madness lies, with a host of different versions around. :) I think, if it was to be specified for this project, then it would have to be with the standard firmware only otherwise compatibility between machines is broken.

Hmmm...
The JDY-40 fits the board quite nicely and can be plug-in if you use 2mm headers.
