Wow, thank you all for the information!
Im learning slowly so this was really helpful!

For ease i'll probably try out the gpio-1-to-2-extender first - see if that works!

It won't. That's a passive device that has multiple male pins connected in parallel to each female pin. If a pin is "claimed" by board A it still can't be used by board B.

AIUI, the only pins that can be used with multiple devices apart from power and ground are the I2C pins and the SPI MISO and MOSI pins (not the chip select) and only when working in thos emodes as that's how those interfaces were designed.
Ah ok, that mostly makes sense. Although alot of this in general doesnt make sense to me haha.
I have a small project im diving into for fun, but I intend to enrole on a fundamentals course soon. Apreciate the patience :)

Im now looking at something like this to allow me to connect the screen + a few other jumper wire bits like buttons: https://thepihut.com/products/breakout-pizero
I wonder if this would have the same issue?:
