Former fire marshal here.

General home: Yes, ABC good around the house. Also, water ones, known at PW extinguishers. We carried them on all our apparatus. Only good for A class fires (solids).

Kitchen: K Class for cooking fires.

Garage: You can have ABC, but remember not use on an engine. It will work, but mess up the engine due to residue.

A halon extinguisher, which is BC, works great in engine bays and leaves no residue. They have been banned for most applications due to environmental damage, but there is likely a replacement product. Not sure what it is.

Note: In my experience, so many extinguishers fail to work when needed from age, corrosion, etc. From my memory, all extinguishers needed to be serviced (recharged / replaced) and tagged annually for businesses.
