Here's a video of a cold boot of my system (sorry for poor quality). I think that the trick is to make sure your monitor is fully awake before booting your computer. By "fully awake", I mean not in sleep mode.
Here are my BIOS settings:

As previously stated, as of macOS 10.14.2, 9th gen CPU users need to spoof 8th gen ig-platform-id:

Thanks for the screenshots and the video, it looks like the option to set the primary graphics is also gone from your BIOS settings, so at least I know it's not specific to my BIOS settings. But it does seem like it's something specific to my setup because I don't seem to be able to get a POST display when multi-monitor is enabled (works fine when multi-monitor is disabled). Tried keeping the monitor powered up during POST per your suggestion, as well as a different GPU, without any success. I might try a BIOS refresh or rollback if I can't make any further progress.
I do have the 8th gen ig-platform-id spoofed per your initial setup post, the iGPU shows up as "Intel Graphics CFL" or something like that, and it does show up in the system info tab. Quicksync h.264 encoding is definitely enabled, and Intel Power Gadget shows appropriate ramp up/down of the IGFX.
