You know there is a book, seriously, not trying to dismiss your questions, called “Einstein for dummies”, that you can probably find at your local library. I already said I am somewhat at my limit of explaining the discoveries of perhaps the most gifted man in history. I wont waste any of my life trying to dispute something Einstein said. I think I would ultimately lose that battle.
E = mc^2 is about matter energy coversion. Its a ratio. Its separate from the physical limitation of the velocities of matter.

And why wouldn’t expansion of the universe, a rate, ALSO be [somewhat] separate from limitation of the velocities of matter?
{To be technical it would actually be dependent because the two velocities of the edges of the universe could ONLY be, at most, twice the speed of light... if you fire two identical guns opposite each other the bullets are, in effect, traveling 2x a single bullets speed away from the other. This is the principal behind super-colliders where both particles are accelerated to near-lightspeed (though opposite to each other); F = ma is STILL in effect so the [theoretical] goal is to get the a to be as close to -c as possible for both particles. IE the closer to c they can accelerate these particles before colliding them the more Force the collision has... and that force is what they’re trying to use to break the particles into smaller (and theoretical) particles}
