I still don't understand why you need the entire function to be
wrapped in with-selected-window.

I don't understand: I thought we were talking about causing the other
window to do something without the user selecting that window.  So why
does it matter where input goes? what input do you want to go to the
non-selected window or frame?

For example, the command "M-PgUp" scrolls "the other" window without
selecting it, and I don't want in this case to have input switched to
that other window.  Same will be my expectation when there will be a
command to show me the source of a function whose doc string is
displayed in the *Help* buffer shown in the other window: I want just
to see the source in that other window, I don't want to start typing
there.

What am I missing or misunderstanding?  Why are you suddenly talking
about redirecting input?

You are talking about a situation where multiple *Help* windows are
shown?
