Step 1: In a medium pot, bring chicken broth and water to a rolling boil over high heat. Stir in quick grits and garlic powder. Cover, reduce heat to medium-low, and simmer for 5-6 minutes, stirring occasionally, until liquid is absorbed and grits are tender. Remove from heat, stir in heavy cream and shredded cheddar cheese until melted and creamy. Cover and set aside.
Step 2: Heat a large skillet over medium-high heat. Cook thick-sliced bacon in a single layer until perfectly crispy. Transfer bacon to a paper towel-lined plate to drain. Leave enough bacon grease in the skillet to coat the bottom. Crumble bacon once cool and set aside for garnish.
Step 3: Pat shrimp thoroughly dry. In a bowl, sprinkle shrimp with flour, smoked paprika, oregano, and salt; toss to coat evenly. Reheat bacon grease in the skillet over medium heat. Arrange seasoned shrimp in a single layer (in batches if needed) and cook for about 2 minutes per side until pink and opaque. Transfer cooked shrimp to a clean plate and immediately squeeze fresh lemon juice over them. Set aside.
Step 4: In the same skillet, melt 4 tbsp butter over medium heat. Add minced garlic and finely chopped green onions (white and light green parts). Sauté for 1-2 minutes until fragrant and softened. Stir in 1 tbsp all-purpose flour and cook for another minute, stirring constantly. Pour in clam juice, whisking constantly to prevent lumps. Bring to a gentle boil, stirring, until sauce thickens.
Step 5: Turn off the heat under the skillet. Stir in honey, the remaining fresh lemon juice, and hot sauce (if using). Add a pinch of salt to taste. Return cooked shrimp to the skillet and gently stir to coat completely with the sauce.
Step 6: Spoon generous portions of warm, cheesy grits into bowls. Top with a heaping helping of the shrimp mixture, drizzling plenty of the buttery sauce over everything. Finish with reserved crumbled bacon and a sprinkle of dark green onions. Serve immediately.
