Vertical spacing around plain display math vs `amsmath` environments such as `gather`
The space above a math display is either \abovedisplayskip or \abovedisplayshortskip depending on whether the last line of the previous paragraph overlaps the equation.
However AMS alignments are ...

Multi-Line Equation Alignment Across 5 Lines
I'd use split and vertically align all the + signs. A local command easily does the job, and \pder vastly simplifies the input.

Insert equation labels inside a tikz(cd) diagram
The easiest solution would be where the tikzcd is using an unnumbered display math environment, i.e. equation* or \[ … \] and we will just place nodes with the equation number in it.
This seems to be ...

You asked,
Is there a solution to this?
Short answer: Yes.

Breaking Long Radical Over Multiple Lines
Rather than splitting the contents of the radical I'd use a fractional exponent. By nesting split inside align, you get the equation numbers centered between the lines.
Don't use pxfonts, that's ...

Breaking Long Radical Over Multiple Lines
Instead of creating superlong lines (vinculi?) which span two lines, I suggest you switch to [...]^{1/2} notation, with the opening bracket on one line and the ]^{1/2} term on the other.
