First, this is NOT about deck building…this is about what objectives to choose when you pull your first 4 (and have to discard 1).
What is the strategy? I would say the most obvious is, if you have an objective that can "pay" two resources, it is an obvious choice to NOT be discarded. Is this always the case?
What else are you looking for in your opening objectives? Card Draw? Resource?
Is there really a use for the "blank" objectives?
