Best practices regarding Adjoint, when should it be used instead of Array, best way to 'style it out'

the best practice way of dealing with [unwanted] Adjoints?

Use copy to materialize it, just as it says in in the docs.

@mkarikom

why I would want to potentially write functions that accept/return Adjoint instead of just array?

You really need to post your code here, because I don’t see a reason a priori for a function to not accept Adjoints.

If you use arrays and not matrices (i.e. you don’t care about the algebraic structure, which seems to be your case), you should use permutedims.
