All these questions, OD - do you have any SOPs in whichever company you fly for?

If so, 'refer' your 'questioning' colleagues to those.
If not, my preference would be: Autobrake as necessary eg if you are vacating at the end of a 10,000ft runway, none. Assuming you do fly a 737, you should have access to a QRP and if you wish/need/have to use autobrake, you should use the autobrake landing roll figures in that for the
intended exit point. It can always be cancelled once things are 'under control' or change.
5nm level in which we bustet 40kt speed and 2nm at 210.
- I don't understand that.
Now, depending on which ?seat you are in?
a) If left, take control if you don't 'like' the way the F/O is flying.
b) If right, say 'You have control'.
Then discuss it on the ground - NOT in the air.
Simple, no?
