I thought that it could be an issue of Emacs-side because:
a) What straight.el does is just `eval' of autoload forms;
b) M-. failure is reproducible without straight.el;
c) Autoloading itself works fine even if autoload forms are evaluated
without `load';
d) It works well with Emacs <= 28;

No, I didn't. But the following Github issue might be the same:
C-h f for some functions link to the loading file instead of their source
file:
https://github.com/radian-software/straight.el/issues/1022
I tried to find more simple recipe. Could you try this with emacs-29
or master?
----------------------------------------
1. Create the following file
~/.emacs.d/site-lisp/loadhist--foo.el
#+begin_src emacs-lisp
(defun loadhist--foo-inc (x) (1+ x))
(provide 'loadhist--foo)
#+end_src
----------------------------------------
2. emacs -Q
----------------------------------------
3. Insert the following to *scratch*
#+begin_src emacs-lisp
(setq load-path (cons (locate-user-emacs-file "site-lisp") load-path))
(autoload 'loadhist--foo-inc "loadhist--foo")
(message "(loadhist--foo-inc 1): %s" (loadhist--foo-inc 1))
#+end_src
----------------------------------------
4. In *scratch*, M-x eval-buffer
----------------------------------------
5. M-. on `loadhist--foo-inc'
=>
xref--not-found-error: No definitions found for: loadhist--foo-inc
----------------------------------------
6. In *scratch*, M-x eval-buffer again
----------------------------------------
5. M-. on `loadhist--foo-inc'
=>
Jumps to defun in ~/.emacs.d/site-lisp/loadhist--foo.el
----------------------------------------
