Should “arbitrary” suffice on its own, or does it make sense to include “any?”
If you leave out the any in that sentence, you could be talking about a known set of criteria that happen to be arbitrarily selected. Add it, and you are broadening the scope to include criteria that are not specific, germane, or qualified in some way.
My Webster’s defines arbitrary as
based on random choice or personal whim, rather than any reason or system
I suspect you may be worried that arbitrary may mean the same thing as any, but it does not. There is no sense of randomness to the term any; it only expresses a degree of inclusiveness.
