Toast the walnuts in a dry skillet over medium heat until fragrant and lightly browned, 3–4 minutes; set aside to cool. In a small bowl, whisk together the apple cider vinegar, Dijon, whole-grain mustard, honey, thyme, lemon zest, a pinch of salt, and several grinds of black pepper. Slowly whisk in the olive oil until emulsified. In a large bowl, combine the arugula, shaved fennel, celery, radicchio, shallot, and a tablespoon of chopped fennel fronds. Drizzle with enough vinaigrette to lightly coat and toss gently. Transfer to a platter, scatter the toasted walnuts and shaved cheese over the top, and finish with a crack of black pepper. Serve immediately.
