Virtually all descend brands support multiple pairing and fast switching nowadays. This is not a AirPods advantage. AirPods miserably fail at this as soon as you use them on anything non Apple.

Nearby Share works exactly the same than AirDrop with regards to pair to pair mode on supporting device. It also works on anything supporting one of its client which covers a lot of material.

Find my: Google has exactly the same functionality and has had it for years.

You are completely disconnected from the state of the art. Meanwhile it’s 2025 and iOS still can’t properly deal with notifications.
