If you're looking for a SBC with mature software from Pine64, I would suggest the RockPro64. As stated here[1], it's certified as SystemReady IR:
There should be a wide range of options for OS for this SBC, although my experience is only with Armbian on it.
I had one which worked fine as a NAS for a year, then I got bored with it and gave it away. Now I'm waiting for software support for my Quartz64 model A (8GB ram) to build a new NAS (it's not a vital project for me, so I can wait a bit more).
