emacs has the concept of markers, which basically means you can save
positions in the buffer and go back to any saved position anytime. (as
opposed to other editors, which effective has 1 single marker)

The short answer to your question is: type Ctrl+Space to mark a
position. Then, later when you want to jump back to the last marked
position, press Ctrl+x Ctrl+x. Press that again to go back to last
cursor position.

The saved positions is called the mark ring.
One should be able to mark multiple positions and cycle them...
despite me using emacs for 10 years and attempted to read the marker
cycle usage documentation a few times but never really understand it
exactly to actually use it ...

You might try to read the doc yourself. Type Alt+x info, then node
“(emacs)Mark”.
