Have you tried using the expressionz($geometry)?

Yes it only returns Null from the vector layer, after extracting the nodes the Z coordinate is lost and I am only left with X & Y

I have a similar problem. To get Z coordinate from polygons you need to tell what is the vertice you want Z. z(point_n($geometry ,1)) The problem while calculating Z coordinate from polygons is that Z returned is an integer. I need Z real, i´ve tryed a lot of other ways inside calculator and keep getting an integer.

You could try How to „extract“ z-values ? to open the attribute-table, go directly into the field-calculator. Within the geometry-functions you will find z
Just calculate z on the geometry: z ($geometry)
