There is no short answer but in the three flag carriers I worked for it was go around and sort it out in the stack except for one operator when below 200ft.
Considerations were;
aircraft configuration.
crosswind limitation.
WAT limitations in the event of a low go around (know one crew who got it wrong in Madrid who had a low missed approach caused by ATC and found that they couldn't climb!) (cleaned up/accelerated to 200+ and followed the valleys)
runway state.
New approach speeds./minimums (and poss runway length rgd.)
Auto-throttle not certified.
Auto pilot not certified.
depending on the engine/type - no anti skid and limited nosewheel steering.
Auto brake?
Auto ground spoilers?
No doubt I have forgotten some other considerations like start the apu.........
Not forgetting who is reading the checklists , monitoring the flying, calculating the speeds, talking to atc......
