I would also recommend not overthinking what kind of ammo she should shoot in the revolver ( and stay away from any +p's -- because they tend to be real "snappy" over the more traditional rounds in that caliber).
In .38 spl or .357 Mag....I'd recommend staying with the traditional bullet in that caliber - with rounds in 158gr bullets. ( most of us will practice with 158gr FMJ / and carry a 158 gr JHP or JSP for defense - in 38spl and .357 Mag).... 110gr or 124gr ...tend to be more snappy as well.
Most importantly - urge her to go to the range on a routine basis ( couple of times a month or even once a week, until she is really familiar with the weapon she chooses)...and a box or two, at the most is enough, for her to run thru some practice ....maybe even meet a friend in her age group that likes to go as well...so they can encourage each other - and train together. And no matter what - make sure she has fun with the process ( picking out the gun / and training )!
