Arrange the baguette slices on a sheet pan. Drizzle with olive oil and season with flaky salt and dried parsley. Bake until crisp and golden at the edges, 8 to 10 minutes.
Meanwhile, combine the cucumbers, cherry tomatoes, red onion, basil, dill, cilantro, olive oil, salt, vinegar, and lemon juice in a medium bowl. Toss until evenly coated.
Rub the warm toasts with the garlic cloves. Spread each slice with garlic-dill cheese, then spoon the salad over the top. Serve immediately.
