Question 1

Has anyone else been able to get Audio to work with the default speakers using line out from PC to Headphone jack?

I still have no luck getting it to work.

HDMI Audio/Video works for stuff like my Nintendo Switch. But due to annoying driver issues (linux) I have not been able to get it to properly do audio with 3.5mm cable.

I also cannot get audio to pass-through via HDMI or Display Port from PC to the Monitor.

I had to figure this out slowly. No need to use cable from the line out.  Audio info comes out of your GPU through the same displayport cable that carries the video.  You just have to look into the sound settings of your computer and try the different audio output options so that sound comes out of the speakers present on the monitors.  On my computer, the way they were named was not helpful, so I had to try them all out until one of them worked.
