Librewolf or Icecat or Mullvad Browser or some version of hardened Firefox. Which is the most secure?

Secure from what

>icecat
For whatever reason they don't provide up to date binaries. The project isn't dead if you check its savannah page, they still keep it up to date, but you'd have to compile it from source.
>mullvad
never tried it
>librewolf
Hardened firefox with sane defaults that don't break stuff. You can probably harden it more if you wanted too.

As another option, I'd look into user.js files for trannyfox. Their benefit, for those inclined, would be that you'd actually learn how to harden it and what each option does. You can customize it to fit your needs and build it up. Ofcourse this is all assuming you're willing to read the file and study it. A nice one with sane defaults is a project called betterfox, they also have good documentation which shows you what extra options you might want to look into and how to edit the file.

least trackable and fingerprintable

LibreWolf. IceCat hasn't been updated for years and the rest of the FF forks look like honeypots. LibreWolf is the only sane option IMHO.

from sense of constant paranoia and insecureness about someone could now you gooned to femboys
or from sense of not being like others

>fingerprintable
Fingerprinting is one of the most difficult things to avoid.
Using anyone of your three choices would narrow you down almost immediately.
Since one of the major fingerprinting aspects is the browser you use. How many people use icecat, librewolf, or mullvad?
