Bite will beat the first hit of Fsmash, though you might take damage, while if they space the second hit correctly, they won't get eaten.
The only experience I have with Wolf is a lot of bairs, somewhat spam with lasers, and spaced Fsmashes (kinda like a Marth, if you position yourself so that they can tipper Fsmash you on purpose, they will Fsmash 9 times outta 10.)
Watch out in case the Wolf knows how to light-step, or whatever they call it. They can cancel their side-B on the ledge on purpose, and if they know what they're doing, they can catch you by surprise.
Wolf will have a hard time killing us, and doesn't have many options when knocked offstage. 60-40.
And just so this can be clear, what is the difference of air SPEED and air ACCELERATION? Is speed vertical, while acceleration is horizontal?
