Remove stems and seeds from the guajillo and ancho chilies, then toast them in a dry pan over medium heat until fragrant.
Place toasted chilies in a blender with the beef bone broth, garlic, cumin, oregano, and cinnamon, then blend until completely smooth.
Season the beef chuck with sea salt and black pepper, then sear in a heavy pot over medium-high heat until browned on all sides.
Pour the blended chili sauce over the beef, bring to a low simmer, cover, and cook until the beef is tender and easily shredded.
Remove the beef from the pot, shred it using two forks, and return a small amount of the liquid to the meat to keep it moist.
Dip the corn tortillas into the top of the remaining liquid (the consommé), place them in a skillet, top with shredded beef and Oaxaca cheese, and fold.
Cook the tacos until the cheese is melted and the tortillas are slightly crisp, then serve with a small bowl of the remaining consommé, fresh cilantro, minced onion, and a lime wedge.
