Make the slaw. In a medium bowl, combine shredded cabbage, mayonnaise, lime juice, honey, and cumin. Toss until well coated. Season with salt and pepper to taste. Set aside in the fridge while you cook the shrimp.
Season the shrimp. Pat shrimp dry with paper towels. In a large bowl, toss shrimp with Cajun seasoning, smoked paprika, garlic powder, salt, and pepper until evenly coated.
Cook the shrimp. Heat olive oil in a large skillet over medium-high heat. Add seasoned shrimp in a single layer (work in batches if needed) and cook for 2-3 minutes per side until pink, opaque, and slightly charred. Don't overcook—they should be tender and juicy.
Warm the tortillas. While the shrimp cook, warm tortillas in a dry skillet, in the microwave wrapped in a damp paper towel, or directly over a gas flame for a slight char.
Assemble the tacos. Place a generous amount of creamy slaw on each tortilla. Top with Cajun shrimp, sliced avocado, cherry tomatoes, and fresh cilantro.
Serve. Serve immediately with lime wedges and hot sauce on the side. Squeeze fresh lime over the tacos before eating for maximum flavor.
