Droplet is the "popular" middle ground. Contact is completely overshadowed by both types of air travel unless air travel is either completely out of the picture (non-respiratory viruses like various herpes) or if the virus particles excel at durability outside the body (e.g. the rhinovirus family, whereas being bad at this is an outcome of the defining property of corona viruses, they are short-"lived" almost by definition).

And droplet basically translates to: "yes, masks would help, but simply keeping a few feet of distance will be just as good". Unfortunately, distance does to aerosol transmission what soda cans do to a wildfire.
