How to fix heavy items to metal stud walls?

[imarshallwidjaj]

I just moved into my new apartment and have a few different medium (shelves) to heavy (TV, floating desk) duty things I want to fix to my wall, but with the way my walls are setup I have no idea what's the best way to do that.

I was able to take a peak when they installed the A/C. The walls in the whole place are setup like this as far as I know with some areas having insulation too in the void. And the studs (are they even studs?) are metal and bracketed into the concrete and non structural.

What are the options I should have to do all my fixing needs? Do I fix to drywall? Metal stud? Or into concrete? And how? When fixing into concrete won't the screw pull the drywall into the void and crack it?

TIA!
