Ask her if she wants to switch to IOS first then bring her to a store for her to try an iPhone to see if she likes it or if you are using one ,you can let her try yours.
If she doesn’t want to then just stick to Android and buy her one of the model. But if she decides to make the switch, I recommend going for iPhone 15s (if your budget allows you for it) mainly for the USB C as she would already have alot of it laying around.
Random cables of usb c that are already laying around my house, plus one usb c (that supports 5gbps transfer speeds) for transfer data.
