I suspect that the answer to your question as to who does what is to
some extent dependent on each individual crew combination.

No doubt. I simply wanted to get an idea of what current practices
are.

CRM came about because in the past, sometimes the PIC was "too much" in
command, intimidating the rest of the flight crew in such a manner that
they would fear to question inappropriate decisions made by the captain.

That is still true in many parts of the world; CRM has proven to be at
least partially impossible to apply in some regions, where culture
overrides safety (the Far East comes to mind).
