It seems that LP5569, alternative LP55231 nor the option considered in #11 are available really.
As an alternative a GPIO controlled solution has been considered: Using three GPIOs controlling all three LEDs (of the same color) together. However, this requires external LED drivers, does not allow dynamic brightness change, and getting the brightness balanced requires testing with resistors etc.
Furthermore debugging showed to be critical: only having software controlled LED, and no LED indicating that the device is running early at boot is annoying.
Decision: Let's populate the regular Raspberry Pi LEDs
Red power LED
Green activity LED
Additional to have some options controlled by Home Assistant (OS), also add a yellow red
