I recently came across upwork and it seems like a perfect platform to find clients and work on similar projects. However, I read a lot of horror stories about it here and elsewhere, with the general opinion being it's best to find clients directly. What are recommended methods to advertise your services to potential (local?) clients in an unobtrusive way?

Other, good freelancers often have more work than they can handle. They're often happy to have colleagues to refer people to. They'll get to know your niche, and can find places to refer you. (and vice-versa, you can refer them...). They also can help you vet the clients, and help figure out who's sketchy and who's a good client.
