It would mean the great filter could be behind us.

I'm not sure how a black hole would help create life, an inbound Planet 9 would certainly be a hinderince to life's existence though.

Maybe it doesn't help create life, but prevents its destruction, like Jupiter protects Earth from asteroids, or has another shielding effect.

Iirc it’s a bit of a myth that Jupiter protects the Earth. It does some sometimes capture objects and send them away from us, but it also sometimes hurls objects straight towards us
