If you google
native white balance of a sensor
You'll get a number of hits. I guess you'd have to read through a few to find your answer.

Some of the hits were my old posts. I never got any answer on this. I guess people never thought about it.

For a given camera, the "native" WB reflects the manufacturer's proprietary internal design (similar to "default") settings - the standard manner in which that camera renders various colors, white and monochrome tones.

Something like "native white balance" could probably have multiple definitions, but I'd be inclined to define it as the white-balance RGB tranformation of (1.0, 1.0, 1.0) from RAW. Doesn't that seem reasonable?
Well, that's been dubbed UniWB, has been a useful concept for a long time and is well understood by the people that use ETTR in order to avoid blowning the highlights in the individual color channels.
Google "UniWB". There's lots of info.

I'd much rather put up with a little extra noise than settling on a white balance I feel is not right for the image. However, armchair photographers usually see it differently - they are more concerned about zoomed-in detail rather than the image as a whole.

UniWB is what I've been using for about a year or more. That along with exposure techniques that utilize the capabilities of the sensor, nail exposures for me consistently.

Why do you hear people say they like Nikon color vs Canon, or Canon vs Nikon. With a ColorChecker from X-Rite you can adjust all brands to produce similar results.

Probably for at least two reasons. First when using the built in auto white balance the results will be unique to one brand or the other, and second each brand has a unique color response curve, and this will affect color and white balance.
And yes, I agree that you can use the CCP to get any camera to produce 100% neutral color, regardless of camera brand. I do it when I have a second shooter at an event, and she/he is using different gear.

Why would a sensor that is capable of delivering a RAW file have to have a native White Balance?
White Balance is something that you apply to the RAW file (either in camera or in post production).
It is an editing down of the RAW file to match what we know about the illumination environment.

Never heard that before... But I've only been shooting digital for about 20 years.
Still, I'd like to see some proof.

This sort of explains the statement, worth reading
