How do you choose your candidate moves?

I see that
Qxf7+ is one of the candidate moves but Bxf7+ is not one of them.
What is the reason?

I think that it is more logical to consider first Bxf7+ and not Qxf7+ that sacrifices the queen or Bh7+
Note that Bxf7+ also can force mate more slowly based on analysis

The only reason that I can understand for not prefering Bxf7+ in the search is the fact that Bxf7+give black 3 legal move when Qxf7+(like Bh7+ give black 2 legal moves) but a rule that always prefers searching first check that restricts the number of moves of the opponent regardless of material seems illogical and when it may be good for some tactical positions I cannot believe it can be good for tactics in general.
