On the Orbi: VLAN1 is primary and where I keep my singleboard computers, my servers, two TVs, X-Box, Switches, and my laptop. VLAN2 is for IoT hubs, cameras, Roomba, etc. VLAN3 is strictly lightbulbs, which sounds ridic but when I did a wifi analysis they really really super really take up a lot of wifi bandwidth, I've been slowly replacing with Hue and other zigbee, but it's in progress. I may move the cameras there as well.
It might be a tangent: In my understanding this does not work as you might think. Unless your Orbi actually uses different radios for the different WiFis they will still have to share all available resources - no matter the SSID. Are there really Orbi devices that use different radios for different SSIDs (apart from the obvious 2,4 GHz and 5 GHz + 5 GHz mesh connection).
Gitlab CI/CD pipelines are my go-to tool. At work we self host an instance, for personal projects I use gitlab.com.
