Always a risk of stereotyping the lady - apologies in advance.
However, with any learner, low recoil, low muzzle blast, ease of use and fit are the keys.
Low weight and low recoil can be mutually exclusive.
Do not recognise everything on your list, but if a simple .22 RF is not available, a .223 - The Ruger Mini14 would appear to be the choice. From memory these are quite short in the stock?
Care needs to be taken to handle the action/ mechanism side of things until the novice gains confidence. Definately don't start with a full mag!
Sounds daft, but always remember ladies are different. Sometimes things ( hint - chest level ) can get in the way of shouldering a rifle. Small details count - certain ear-rings can be uncomfortable under ear defenders and may be driven into the face/ ear under recoil.
I have been advised several times that bar strap buckles are very painful if they trap skin on recoil etc.
For a novice, electronic ear defenders are great ( and the instructor ) it escapes the closed in feeling, allows you to instruct calmly - no need to shout etc and keeps everything much closer to 'normal'.
Try to go somewhere quiet - a lady on the range often attracts the worse kind of ninja warrior wannabe. Machismo shouldn't be any part of the process.
Hopefully I have offended no ladies - certainly not intended.Finally, other than unavoidable physiology, treat as a novice first - irrespective of gender.
