Dice mango, pineapple, and watermelon into uniform bite-size pieces, approximately 1/2-inch cubes.
Slice strawberries into quarters or halves depending on their size.
Combine all the prepared fruit in a large mixing bowl.
In a small bowl, whisk together the fresh lime juice and honey until well combined.
Drizzle the lime-honey mixture over the fruit, making sure to distribute it evenly.
Toss the salad gently with a large spoon to coat all fruit pieces evenly with the dressing.
Add chopped cilantro and a pinch of sea salt.
Mix everything lightly one final time. If using optional ingredients like Tajín or chili powder, sprinkle them on now.
Cover and refrigerate for at least 15 minutes before serving to allow the flavors to meld together.
