There are so many ways to fingerprint a browser and new ones are introduced and discovered all the time. The best protection against fingerprinting isn't to try to be the same as everyone else and pray that you've somehow accounted for every possibility, but to always present as a different browser. It can only take changing a single data point to look like a new browser/device, although you still have other things like your IP address which can associate fingerprints with each other. A VPN can give you a new IP every day, or every few hours which can help.
