OK, here you go. About as simple as it gets.
I assure you that the connections via the alligator clips are fine. As I originally stated, I made sure connections are good and tested voltage to a conducting metal piece inside the plastic connector further toward the servo. I also tested continuity of every wire, and even replaced all wires just to be sure. I also tested two other servo motors (and two other Nano ESP32's) for completeness. Just so you understand, I have a fair amount of experience with electronics and software development, so do understand a thing or two. I also want to reiterate that if I keep everything exactly as it is and pull the ground and PWM leads from the breadboard and attach them to my Raspberry Pi, it works fine.
Thank you!
