I'm running Emacs 28 and cannot reproduce the issue you observe. Running
emacs -Q I find M-j is bound to

M-j runs the command default-indent-new-line (found in global-map),
which is an interactive compiled Lisp function in ‘simple.el’.

It is bound to C-M-j, M-j.

(default-indent-new-line &optional SOFT FORCE)

Break line at point and indent.
If a comment syntax is defined, call ‘comment-line-break-function’.

The inserted newline is marked hard if variable ‘use-hard-newlines’ is true,
unless optional argument SOFT is non-nil.

This binding is the same inside and outside of org mode. This is with
org version

Org mode version 9.5 (release_9.5-72-gc5d6656 @ 
/usr/local/share/emacs/28.0.60/lisp/org/)

and Emacs version

GNU Emacs 28.0.60 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.30,
cairo version 1.16.0) of 2021-11-26

Note that C-j in org mode is different from 'normal' C-j in that it is
bound to org-return-and-maybe-indent. If you want M-j to act like C-j in
org mode, you would need to rebind M-j to org-return-and-maybe-indent in
an appropriate org mode startup hook.
