Roux First Block LD Pair or F2L Pair?

Sometimes during inspection I will have an LD Pair and an F2L Pair that I can use to start my First Block. In general does one way work out better than the other?

In this scramble I have the Red/Blue F2L pair I can match to the blue center. I also have the Orange/White LD pair (I’m disregarding the Yellow/Green LD Pair on top for now, but that could be used as well). The one possible disadvantage I can think of by using the F2L pair is I would also have to match up the corresponding LD pair at the same time for better efficiency (which may not be a disadvantage depending on the moves).

It depends. When I have a f2l pair I figure how much it takes to insert the DL edge and see if that’s easier than to set the DL edge and make a pair

Same as above : it depends.
Where are the others pieces of the FB? is the "first square" easier to do with one or the other? if so, is the last pair easy to make/insert?

The same should apply to the SB: if a pair is already done, or the BR edge is already in place for instance.
