Oven Vent—What CFM Is Too Much

I’ve got an old home in NOLA.

Putting in a new hood for my oven. I can’t get a feel for what I need in terms of pulling power. I just want to be able to fry fish and sear steaks on my stovetop without the fire alarms going off.

I’m reading that some of the bigger hoods need “makeup air.” The hood I’m looking at now moves 700 CFM at the high setting.

Any advice appreciated.
