I prefer small dogs.
For obvious reasons .

Just out of persnicketiness I do want to make the point that most large dogs are perfectly safe. And I’ve met far more improperly trained small dogs than I’ve ever met large dogs that scare me. I’ve only ever been bitten by small dogs.
Feel free to choose whatever dog you want. I’m not trying to change your point of view on that. But, I think you’re doing responsible dog owners a disservice when you pick a corner case like that to explain why you think large dogs are dangerous.
On to the OP:
Growing up I lived with a 70 lb German Shepherd/Husky mix. Then we got a 60 lb Brittany. Both what I’d consider medium dogs.
However recently I’ve lived with a housemate who has Great Danes. I’ll second what most of the other posters have been saying about size and life-expectancy correllations, and activity levels.
I now admit that there are sizes beyond which I think a dog shouldn’t be. First off, the Great Danes I’ve known were all marshmallows. They’d bark if there were strangers at the door, but never had any problems with them attacking anyone. And the deterrent effect cannot be overestimated, IMNSHO.
The problem with them comes from their size. First you’re going to get people who assume that any dog they can’t kick away is automatically dangerous. So, people, Police, and the courts view a Great Dane running about as a threat, where other breeds get second chances. (And not without justification, I’ll add - at least with the assumption of threat for a Great Dane running off on its own.)
Secondly, they’re awkward animals. Their head can be in your lap, behaving as well as you please. And their tail wagging, in the next room (It was a small house.) will knock all the mail onto the floor, along with your drink. Great Dane-proofing a house is almost as much of a challenge as toddler-proofing one. Secondly, you can’t, unless the dog is superbly trained, not simply well trained, have dinner on the table comfortably with the dog in the house. I don’t mean that the dog will steal the food - a well trained dog will know better. But unless the Dane is superbly trained, he won’t be able to resist sniffing the food.
From above it. At about two inches distance.
Really, IMNSHO, dogs and humans get along much better if the dog cannot eat off the dining room table without jumping up onto it.
