Great write-up. Next logical step is adding Bluetooth support so you can use it on the Switch: https://www.instructables.com/DIY-ESP32-Bluetooth-GamePad-fo...

Don't forget that these controllers operate at 5V logic and the ESP32 at 3.3V. Supposedly the ESP32 can tolerate 5V inputs [0], but it's probably best to put a level shifter between the two.
