To be honest, most conceal carry course classes don’t teach you much beyond common sense gun safety. At least that was the case with mine. Taking the time to actually go out to a shooting range every once in a while is going to be much more effective if it ever came down to her having to use the firearm.
Getting familiar with how the gun handles, operates, the weight, the recoil, the noise, the muzzle flash, the trigger pull, are all very important things to get comfortable with. For most women who are first time shooters and are simply looking for a lightweight and concealable firearm, I’d probably go with something like a Ruger LCR chambered in .38 special.
Even a small woman (like your daughter at 5’5” 97 lbs) should easily be able to handle it. I have seen some smaller women who had problems with being able to fully pull back the slide of various semi auto pistols. That, and the fact that revolvers are far more simplistic, would seem a good choice for her.
If she is able to get free help from your local law enforcement and practicing every so often, then she should be fine without further classes.
