ELI5: Why do aircraft cockpits have so many buttons and switches? What do all those actually control and are they all used?

They all have a function yes - aircraft builders aren't in the habit of including buttons et al just for decoration.  But bear in mind that redundancy / duplication is a key safety feature in aircraft, so you can pretty much divide the number you see by two to get the number of distinct functions.

  Some of them are "just" monitoring different states (fuel, hydraulics, electricical systems etc) in order to give informationm should anything not be as it should, rather than having a direct purpose in flying the aircraft. Some are for navigation, others for flight control...
