re: Capacitors

Each unit will use different rated capacitors (some still have separate caps for the compressor and fan).
There are maybe half a dozen different caps that are extremely common at best. The values are printed on the side, just match the values and you should be golden. Take a pic of the values and the wiring and keep it (it can/will save a lot of hassle later).
EDIT: Forgot, grab one for (each) air handler blower motor as well, should only need to remove a few screws to gain access to the squirrel cage, cap is often fastened to the outside of the blower.

Just a note/add on, PSC blower motors found in “older” or many “base” model air handlers do have a run capacitor, but EMC blower motors found in variable speed, constant torque, or newer HVACs do not have a capacitor. As I recall, as of 2020 PSC motors are no longer used in new HVAC air handlers, only EMC motors.
