I don't think your question, or rather request, has any sensible answer.
There is no such thing as a "universal" PATH that applies to all programs. Some programs will inherit the PATH (and/or the whole environment) of their parent process, others won't.
Some programs will apply restrictions to the environment they get (e.g. sudo) and/or load optional environments which will override the default (e.g. ~/.ssh/environment).
Even if you only focus on terminals, some will run your shell as a login shell, and others won't.
So just make sure that in *your* system the PATH for *your* particular program is set correctly.
Note that in general there's absolutely no need to adjust anything, as the PATH is rather static (mostly /usr/local/bin, /usr/bin, /bin, and /usr/local/sbin, /usr/sbin and /sbin if root). Also /usr/local/games and /usr/games is rather common.
Normally ~/.local/bin and/or ~/bin if they exist will be added to the PATH, but only for interactive shells (at .profile).
So, please ask if you have a specific question or problem.
Maybe it's even worth opening a new thread, as this one was about the OP not reading the manual, which inevitably leads to the classic "su vs su -" misunderstanding.
