My GenZ Ladies all carry/wear small backpacks rather than purses, which are a little more forgiving for someone who wants to keep something on hand. There's a decent chance the camera-inclined will have one with them, and if not they might have a Switch or a Surface Pro on hand. Half of a kilogram doesn't seem like insanity for them.
I really like a Ricoh GR III for a fairly small point and shoot body. They're not much bigger than a pack of smokes and they have a 28mm/2.8 lens, which is a decent compromise for vlogging and portraits.
I don't completely hate Action Cams (what that Sony thing is) but they have tiny sensors and they tend to make noisy output whether they're used for photos or video. Your guy says it's a 1" sensor and that IS bigger than a GoPro, but for $700, just go buy five Samsung S20s and a couple Otterboxes for them. I suspect the overall output will be similar and the controls will be much more familiar to your daughter, and then she'll get all the filters and shit the kids like and ultimately focus assist and more flexible lens options.
Samsung actually did make a Camera that ran Android. It's kind of a cool concept, but it never got any software updates, but it does have a fairly versatile zoom lens and they still sell for $200. It's phone sized but about three times as thick.
