Fitbit Premium is completely independent of the scale, so that should have no impact whatsoever on your decision. The same is true for your Pixel Watch 4: it's a completely independent device that has absolutely no bearing on anything with the scale. With that said, I've heard that Withings has a scale that might be worth looking into. I can't speak from personal experience, but that's what I've heard.
