Since we have on board eMMC, we can preload something, so we choose to work with the popular Twister OS, based on Armbian, as the default shipping OS for the 4 Plus series. PiLab team did a great job based on the solid work from the Armbian team bringing recent kernel, HW decoding, GPU acceleration to the ROCK Pi Plus. There are many more in Twister OS for you to discover, just try it yoursef.
