When cooked ,I can't picture much difference in holding time,between pork and beef.
Cryovac fresh-yes.
Just habit,I try to get mine out of the refrig by the 4-5 day mark.
Quality tends to suffer ,if feeding others,sooner.
Not to say that I never found a piece at 7 days,gently reheated,very thoroughly,moisturized it and got by.
