The reality is that the happy medium is.. the happy medium. In an ideal world your job involves some amount of physical movement as well as rest time, going all in on either isn't ideal.
That said, the desk job is probably the better bargain of the two since you can always do your moving around outside of work hours, however you can't rest more to make up for overworking yourself physically.
