Correct me if I'm wrong but doesn't the Bekenstein bound exhibit a more or
less intimate relationship with the size of the universe since its reliant
on lowest possible energy?

Its a valid question, you can read a summary here that talks about it:

I dont know how much background in math you have but it gets into topography
a bit.
