Before you go further down this rabbit hole, I suggest to try setting
scroll-conservatively to a smaller value, like 30. If that does what
you want, and doesn't cause recentering in too many other use cases,
you are done without any changes in Emacs.
Once upon a time scroll-conservatively only affected scroll commands,
such as scroll-up etc. But then users came up and demanded that this
setting should affect any motion command, including goto-char etc.
What you see is the consequence of that: Emacs does this by popular
demand. Any command that moves point outside of the window will,
under scroll-conservatively > 100, behave like you see, i.e. always
put point on the last or the first window line.
You could perhaps do what you want by some clever one-time setting in
pre-redisplay-functions. But it might not be easy, I'm afraid,
because you'd need to do that in a way that works only the first time
a buffer is displayed whose place was saved by save-place.
