Since you're (seemingly) already familiar with Arduino, just use that as your framework. You can program the ESP32 in Arduino and access any library you're familiar with as well as handle Wifi. You can buy an RGB matrix on Adafruit and they sell esp32 boards that can drive them directly,so it's essentially plug and play, no hardware knowledge necessary. If you prefer to DIY but still need some guidance, check out this project that documents both hardware and software to achieve something similar to what you want to do (cool looking wifi-connected text display): https://github.com/BlueAndi/esp-rgb-led-matrix https://github.com/BlueAndi/esp-rgb-led-matrix
