Yes, (2) sounds to be the best option.

I appreciate any efforts on that.

Didn't know that! I'm new to LaTeX. Frankly, the log output sounds
very scary to me, as there are lots of warnings there, and debugging
each of them takes time. I don't see any \write18 inside the generated
.tex files or inside the sphinx.sty file. Perhaps it comes from some
Tex extension, like adjustbox?
