6.5 cm, 7mm-08, 243win all good choices. As for rifles, my wife is similar size and has used weatherby Camilla, weatherby compact/youth, and a tikka superlite in a compact stock. The weatherby compact stock and Camilla stock fit her best, and the 20” barrel on those guns make them feel lighter than are to her. This past year she ended up using the tikka superlite in 6.5cm, barrel cut to 21.5” and I had to put a comb riser pad on it to make it fit her. All of these guns work well and may be good options for your daughter. In general, higher comb stock often fit better on the ladies.
