In a small bowl, whisk together mayonnaise, sweet chili sauce, Sriracha, and honey; set aside.
Pat salmon cubes dry with paper towels. In a large bowl, toss salmon with cornstarch, salt, pepper, and garlic powder until well-coated.
Heat neutral oil in a large non-stick skillet over medium-high heat until shimmering.
Place salmon cubes in the skillet in a single layer. Sear for 2 to 3 minutes per side until all surfaces are crispy and golden brown.
Transfer salmon to a clean bowl and gently toss with 3-4 tablespoons of the prepared sauce.
Divide cooked jasmine rice into four serving bowls.
Top each bowl with cucumbers, avocado, carrots, and the crispy salmon bites.
Drizzle remaining sauce over the salmon and vegetables, then garnish with green onions and sesame seeds.
