Traditionally it was by browsing around "More Like This" on something you liked, delving down the rabbit hole. For instance I watched a few European captioned shows, and each of those led to more that I have loved (Dark, Borderliner, Bordertown, Hotel Beau Sejour, River, among many others). Unfortunately many of their interfaces don't support More Like This. Netflix has very poor discoverability, and it has gotten worse, but they have an enormous trove of extraordinary content.
