from a programming point of view, all are the same. But if you want to introduce your kid to play with sensors and other stuff, I'd get Playground Blefruit[1]

Seconded. Pick something with wireless connectivity and lots of on-board sensors/LEDs.

any add-ons that you’d recommend? or other stuff for kids playing with Python?

maybe an arduino board plus a raspberry pi?

Depends on the level of abstraction you and your kid are willing to get into.

Arduino's are lower-level C/C++ which may be a little more complex than CP, but have much broader library support (better intro to EE/embedded).

RPis are much higher level which could be programmed in any language (better intro to CS/Linux).

for kids, so ideally not as low as C++
