Not clear if you use it, but there's a family setting to Google One too at no extra charge. So my wife gets the extra space for the same payment. We use about the same amount of space for photos, so it saved us from each having our own subscription.

I'm not sure if this is related to having a YouTube family subscription but it worked seamlessly for us.

Yes! I discovered this recently when my wife hit 95% of her quota. Remarkably fair and nice feature.
