Here is Samin Nosrat's recipe for sugo, the classic Italian meat sauce that, depending on the region, is also known as Bolognese or ragu. This might not at first seem like a braise -- there's no featured chunk of animal protein -- but the principles are the same: a dice of onions, carrots, and celery; browned meat; a long, slow simmer in liquid. Making this recipe takes a few hours, so I usually prepare a big batch and freeze some of it in containers. Samin's recipe calls for pork and beef, but it can be made with any kind of meat, including chicken, duck, rabbit, or game.
