Shouldn't you use scale for anything coffee related? Spoon is cursed word in coffee world as well as preground
These are all things that come close to a sin with hot brewed coffee, but cold brewing is different.
I’d say French Press brewing is also very forgiving regarding the amount and quality of the grind. A lot of people forget that not everyone uses an espresso machine for their coffee (probably the least forgiving method of making coffee)
I just grab a handful of beans and chuck them in my hand grinder. The amount I can hold without dropping any beans seems to be just right for one cup of cafetiere coffee.
Never tried cold-brew; maybe I'll make some this evening, and try it tomorrow.
