Combine 1 cup long-grain white rice, 2 cups water and ¼ teaspoon salt in a medium saucepan. Bring to a boil, cover, reduce heat to low and cook until tender and water is absorbed, 15 minutes. Let steam off heat for 10 minutes before fluffing.
Combine the paprika, garlic powder, onion powder, oregano, cumin, salt and pepper. Rub the chicken with garlic confit oil, then coat evenly with the spice mixture.
Heat a large skillet or grill pan over medium-high heat. Cook the chicken until well browned and cooked through, 5 to 7 minutes per side, or until the internal temperature reaches 165°F. Let rest.
Toss the warm rice with cilantro, lime juice, salt and pepper. Taste and adjust.
In another bowl, gently mix the mango, red onion, jalapeño if using, cilantro, lime juice and salt.
Whisk the yogurt, cilantro, lime juice, garlic and salt until smooth. Chill until ready to serve.
Spoon the rice onto plates. Top with the chicken, then the mango salsa. Drizzle with the cilantro cream and serve.
