These are all the models less than 5.17.x (which has currently 3 versions) that do azw3. The azw3/KF8 was initially in late 2011 on the app on the Fire Tablet.
I don't think the Paperwhite (6th gen) PW1 does KFX.
KFX seems to be about 2019? It was certainly backported to the Paperwhite gen7 (PW3)

KFX is on 2014 and later models (though it must have been backported in 2018 or 2019)

The Kindle (7, 8 & 9), Kindle Paperwhite (2, 3, 4 & 5), Voyage and Oasis (1, 2 & 3) can display KFX files natively. KFX is Amazon's successor to the AZW3 format.

This has the serial IDs of the Kindle models. The actual official Amazon naming is rubbish.
