You can find a lot of different dev boards with ESP32, like the one you mentioned. There is other with camera, e-paper screen drivers, smaller footprint (Xiao ESP32). The simplest way to program is using Arduino IDE, but I prefer using PlatformIO on VScode. GCC would work. The interface is with the USB port, which is used for COM port or for programming
The easiest way to program it would be using something like Esphome. I think Node Red is another tool that greatly simplifys things, but I haven't had the time to mess with it yet.
