I'd steer away from such a generalisation, for that kind of guesswork won't help you. Rather, so long as you have a good flute, the best buccal solution is a
relaxed, flexible embouchure. I'm not saying anything new, here; this is old hat. Without being relaxed you can't really control your focus well; any power we detect is simply the end result of focus, not a matter of applying force. It's just ... tactical positioning, really. No power required to get there.
Watch any top fluteplayer's face closely; they're not forcing or powering anything. They're not blowing into their flutes; they're breathing (robustly, perhaps, but breathing) into them. Not blowing. Breathing. There's a fundamental and very real difference.
The feeling in the average act of blowing out a candle centers on the buccal cavity and the lips, but commonly the result is comparatively unfocused because the mouth and lips are unrelaxed. Instead, breathe into the flute out from the bottom of your chest (or lower, if that works for you), keep an effortless and open throat, all the while feeling the breath and letting the lips feel almost secondary in importance; that will help relax the mouth so you can get around to the real meat-and-potatoes of focus.
Just my two cents; it worked for me.
