I assume some of the tools you've mentioned randomize the fingerprint instead of just hiding it?

According to Arkenfox user.js the Canvas Fingerprint randomization is caused by Firefoxs Resist Fingerprinting

Of course, if we resist fingerprinting too much, we make ourselves have a unique fingerprint again

Yeah, that's why Tor Browser has such strong privacy. You blend into the crowd because everyone's resistance is the same :)

I'd also rather stand out sometimes by resisting Fingerprinting to much than always being Fingerprinted accurately
