if we were to design an add-on for the face plate ... what connector would I want to put on it to support the wires used? Is it a JST-PH connector?

It depends on the add on, how many pins are we talking about and what type of communication?

you say it depends on "how many pins are we talking about and what type of communication" when it would be the same connector type regardless of the number of pins or use ... please tell me if they are JST-PH connectors or not ... thank you

For the design aspect. It is all is relative to the component. If you have a 3 pin you have to connect into one of the connectors from 4 to 11, 4pin you will connect to 1, 2 or 3. The communication is important because some are better for analog others not and i2C is better in default SDL/SCA in connector 3 but you could change that with code is just more lines. Yes is JST compatible.

What new "add-on" are you thinking of?

It seems they have multiple ways of communication, but they have their own ICSP connector, how you will convert to 4 pins? And do they have micropython support?

Pixy2 can communicate over I2C a custom 10-pin ICSP to 4pin JST-?? cable can be made ... and while their python code is built-up to be used with the LEGO Mindstorms EV3 environment ... it wasn't difficult to port to standard micropython ... I actually used their arduino library (porting line by line to python) as the basis for my code ... and just referenced the python code to tie things together ... wish I knew exactly what JST-?? connector is used for the 4pin side ...

 I haven't seen that type of cable so not sure of the technical details but just checking online it seems people use DuPont cables, you can always cut and solder cables from your kit if you go in this direction.

Looking forward to seeing your code, if it works we could implement for blocks.
