It may not be strictly on topic but is a valuable topic of conversation.
A common theme seems to be that not enough pilots seem to know their autopilots as well as they should - if you're not sure exactly what is going to happen when you push a button - then don't do it or find out before you do.
On a 4-axis AP you have more straightforward options providing everything stays coupled - GA or ALTA would be my preferred options to initiate the Go around.
With 3-axis or hand flying, as long as what you do gets you going safely away from the ground, does it really matter?
I imagine most pilots fly ILS at speeds well above Vy/Vbroc (same thing different terminology) so a speed reduction is probably needed at some stage - especially if you are OEI.
