I have a Logitech k380 which in my opinion does this in an intuitive way.
There’s 3 dedicated buttons for paired Bluetooth devices (fn + 1,2,3) and hitting them just pairs to the device. And you can reassign a button to another device by holding fn+1,2,3.
When you turn it on it pairs to the last device it was paired to.
