Impedance is composed of resistance and reactance. But what actually causes reactance? Is it the V & I phase shift? And is it lower with higher V?

All the "V"s and " I"s, greek letters etc are just numbers. We use them to quantify what happens. They don't really exist, though. What happens is: electrons move. That's what causes electricity. So impedance is caused by electrons and material characteristics.
