My understanding is hawking radiation will produce a rate of mass evaporating that’s fairly consistent over galactic time scales, so you just need to make sure the black hole is big enough to “suck” more mass in via gravitational attraction per given time period than evaporates through hawking radiation.
That’s true the constant rate I mentioned would vary with the surface area of the black hole as it changes but the volume would increase exponentially faster
I know a little bit but I’m not an expert.

I think the bigger they are faster tge evaporate. They lose mass at some ratio between their surface and mass.
Exactly the opposite. The bigger one is, the less it evaporates. Time required to evaporate scales with Mass^3
