This is what I use. Replaced my old Fitbit Aria 2. I weighed in on both scales for about a month, and it was consistently 0.15 kg below, which is good. The body fat measurement was a bit more off, and it varies almost nothing over long periods of time, but I don’t really trust those measurements anyway.
I believe you can set up the scale in GadgetBridge as well, but I have not tried to do that.
It’s known as a beginner-friendly distro, exactly for the reasons you say. There is nothing wrong with using something like that as an intermediate or advanced user if that is what you prefer. You don’t have to go “Well, I have been using Linux for four years now, guess I am an intermediate user so now I have to switch to Arch”
