Just offering some food for thought. Unless you have children running around the house and are looking for a physical safety as a stop-gap until they are old enough to learn, I do not ever see a "need" for those3 features.
I need a pistol with a Manual Safety and a Decocker
For some folks it just gives them peace of mind. Trainig or no training,that little lever sometimes sets them at ease...especially for the novice.
The sad thing is, especially for a novice, those same features that give them "peace of mind" require more training to operate efficiently.
Is there even a pistol on that list that has a manual safety and decocker? I suppose there might be a Sig model out there...
And add me to the list of "why"; just two more things to have to train on.
If you demand these options, I'd go with an FNP-- probably 9mm, if it's for your lady friend. You can carry/bedside the pistol in Condition 1, much like a 1911. The thumb safety doubles as a decocker. Although I suspect if you're that concerned with the feature, Cocked and Locked is not something you'd be comfortable with...
