4. Or perhaps sufficiently advanced technology may only be detectable with magical means?

What is detectable of civilization seems to me to be mostly waste energy that is radiated off into space in one form or another.

As technology becomes more advanced then efficiency becomes higher and higher, eventually efficiency becomes high enough that waste energy is very nearly nil, there's minimal energy to detect.

In space even a remarkably powerful laser beam would be largely undetectable unless you were directly in it.
