Roobert, first, what's the definition of a job? Is it
a process or what it is, technically speaking?

Second, what is it you want to do with it, that cannot be done
from the shell, but it _can_ be done with "shell job control"?

I guess not :)

Again, what commands are we talking about and what do they do?

kill, top, nice and renice deal with processes and they can be
- what am I saying - they ARE - used from the shell. So just
fire up a new pane in tmux and use them all you want, happens
every day.

I just put 'return' as the first line of ~/.zshrc, then
starting with \zsh and doing fg and it still says

  fg: no job control in this shell.

Well, I don't launch zsh, it happens automatically when
a Linux VT, Emacs shell mode, or X terminal emulator
is started.

This function [1] tells if zsh is interactive. And you better
believe it is.

interactive-zsh () {
    [[ $- == *i* ]] && echo 'you better believe it' || echo 'not so'
}
