I think putting a light only is not enough. LEDs at night at home, no matter how weak, are an annoyance. I'd also put in a motion sensor that detects movement around 1.5m from the switch and lighths up the LEDs gracefully. A light sensor to set the strength would also be good. Fallback if any of the sensors are broken: keep them lit on the lowest setting.
IMO you can make things smart, but connectivity is only the answer once you figured out all the other stuff. Otherwise it's like getting the internet on an 8bit Atari.
It’s the best solution that still allows showing state, and is done commonly here.
