It might not be as loud/noticeable on highways because there are other louder noise sources so the tire/brake noise isn’t as noticeable. Try driving with the windows down for 20-30 min on different types of roads and speeds. If the sound is always there without brake use, I’d agree with the foreman - it’s the winter tires. We put winter tires on almost all of our cars and the first thing we notice is the significant increase in tire rumbling-humming sounds. Even brand new winter tires are much noisier than a well worn set of performance tires. The only check I can think of is to remove your winter setup, reinstall your summer setup and go for a drive over the same roads. Noise gone = winter tire setup. If the noise is not gone, then it could be the brakes, wheel bearing(s), etc. I expect the noise to go away (or be faint if the summer setup is well worn with feathering on outer and inner tread blocks). Winter tires, especially Snow and Ice versions, are louder than summer tires
I really appreciate this thorough response. I will of course see what happens when I switch to summer tires and report back. However, I am beginning to think that there is a wheel bearing or brake issue as well. The reason I say that is because I can feel it in the brake pedal when pressing it down to break, particularly at very slow speeds. There’s a certain resistance, like something is dragging or rubbing against the wheel. Never felt it before I had the brake jobs done.

But then again the brake performance is awesome, so maybe I should just ignore it?
