I would avoid +P+ ammo.
Before asking "What ammo should I use?" you should ask "What should ammo do, what shouldn't it do, and how is it tested?" I recommend the following:
Handgun Wounding Factors and Effectiveness from the Firearms Training Unit of the FBI
Basic Wound Ballistic Terminal Performance Facts by Dr. Roberts (DocGKR)
Ordnance gelatin test assessment for rifle and pistol calibers by Dr. Roberts (DocGKR)
What's Wrong With The Wound Ballistics Literature And Why by Dr. Fackler
For specific recommendations I start here:
Service Caliber Handgun Duty and Self-Defense Ammo by Dr. Roberts (DocGKR)
Then here (for 9mm and 380):
