Yet there is still quite a lot of friction.

Airpods have the best support and they still require you to find out how to pair them when you change device and wait.

Keyboard/mouse is insane. If you want to use them with two different laptops.

My mouse (Logitech MX Master) supports Bluetooth. It also supports Logitech' s "Unifying Receiver" and has a button to switch between three different Logitech receivers. I think everyone can guess correctly which of these options just works and always does what you want it to.

To clarify if it's not clear - the button switches between three different receivers, Bluetooth or Logitech unifying receivers. Currently I have 2 BT profiles, and 1 Logitech. The mouse works flawlessly

If it's not obvious, the USB receiver works flawlessly. I occasionally have trouble with Bluetooth not connecting (or randomly disconnecting) with the same mouse, but it mostly works okay.

When I connect my AirPods to my 2015 MBP they don't properly connect unless I open and hover over the speaker icon in the system bar. There's also an issue if I start connection with only the left bud, probably the right bud is the main one?

I think they are symmetrical. You can use both separately, without the other.
