Tbh, in my opinion it kinda depends on the plot.
You all can either agree or disagree to my points. The choice is yours.
Suppose you're writing a medical (or any other modern subject's i.e. STEM, finance, etc. You get the picture.) drama plot, then you gotta be precise as to how the medicines, the operations, the health care system work. Or else no ones' gonna take it as seriously you want it to be. Here, you just care about the numbers.
And if you were writing a history/romance (subjects that are quite sensitive regarding culture and traditions) driven plot, it's best to stay accurate as these topics changes from perspective to perspective. Some may interpreted in this way, or the others in a completely opposite that quite contradicts the previous group's opinion. It's best to find the middle ground as not all of us can interpret or reciprocate the same feelings as the others. This depends a lot on experiences than data could ever comprehend.
So in short : -
Technical genres -> Precision is best suited.
Human genres -> Accuracy is the most appropriate.
