What is this part and does it have to do with my my z-position is messed up?
Limiter Switch/Endstop
That is the lever that is meant to trigger your Z-Endstop. The variant used in your case is on the cheaper end and is meant to look similar to this QIAOH KN12-1 limit switch:

Does moving the z-endstop upwards affect the maximum height of the printable object?
If you move up the end stop such that it raises the nozzle with respect to the build platform you lose height, so basically the answer is yes. But, as seen in your referenced question, your nozzle ...

Is cutting the arm off the Z-axis switch a good idea?
While I haven't seen this on a Z axis for a printer personally, there is no reason it wouldn't work, and would improve your repeatability in theory. Removing the arm on the switch is taking away the ...

Ender 3, why only 3 limit switches?
Because it knows the side of the build volume, all it needs to know is one physical location to home from. So knowing {x,y,z} (0,0,0), and knowing x(max) = 230, y(max) = 230, z(max) = 250, and ...

How could dual end-stop switches on each axis improve the functionality and precision of 3D printers like the Creality Ender 3 V2?
First the questions in the body are addressed:
I realised that there are three end-stop switches, one for each axis, X, Y, and Z. But this only helps to determine the start (0) position of each axis.
