Keep it simple.
You have flap 1 when you set TOGA so the aircraft will go into Go Around mode.
You now have even more time to aviate.
Toga/ srs / ga trk becomes alt* then spd/alt/ ga trk.
Once again push for Nav and you now have green dot speed and managed nav.
What's not to like?
Don't forget the aircraft will go into go around mode on selection of Toga depending on the flap handle position when you start the manouvre.
Activate the approach and have another go.
Always monitor and believe the FMA.
