@Taskerland I think that's a bit person by person not even table by table. I know people who hate speaking in first person and people who love "the bit". You can't enforce that at the table with proscribing against some player styles. I think bringing it all together is the GM's job. That's part of the director role. "Tim likes pretending he is a Piglen Lord, Tony wants to make plans, Poppy wants to do maps of her house, and Ian is a prick" you just juggle it to maximise the groups enjoyment.
