the course say it has to be 3 feet clear in the front and the sides but doesnt say that it has to be three feet above the window as well, i might be being overly specific but is that true?? like for example my arm is probably three feet long so according to those standards i could technically reach out and touch the power line if i wanted to

The first step to EVERYTHING is to fully understand the WHY something is required!
Not understanding is akin to grabbing that power line!

what counts as “an overall jacket”? like a metal conduit or something?

That is correct.
Not a conduit a cable. SE cable would be an example of a cable with an outer jacket. The multiconductor cable without a jacket would be something like triplex drop cable that the utility uses from the pole.
