Wild to limit yourself to what the manufacturers “officially support”. May as well just run macOS with that attitude.

I agree that you shouldn't rule out devices that don't have official support for Linux. And it's amazing that the community brings it to some many devices.

But if you already know at purchase that you'll install Linux on the device, you might as well prefer those with official support rather than just a community port, simply to show support for companies that agree with your priorities.

Also you should inform yourself beforehand. Don't just buy random hardware and then make the surprised pikachu face when it happens not to support Linux.
