I also reckon that the shooting conditions matter too. Most vintage photos that have survived are overexposed and taken in very strong daylight, simply because that was the only way normies could get photos to "work out".
Most amateurs don't understand exposure now, when the cameras make it trivially easy and there's a world of knowledge a google search away.
Now imagine putting a camera with no light meter in the hands of someone as ignorant as your grandparents.
There's a reason why all of these old pics are taken in the front yard at midday, it's because most cameras didn't even have fast enough shutters to create underexposure in that light.
So really the best settings are f/22 and 1/250, on ortho film at midday with an uncoated 3 element normal lense
