Say, would there be any difference between “secession” and asserting, nay, INSISTING on 10th amendment sovereignty and not allowing federal laws outside of Art I Sec 8 to be enforced within the state?

Three big differences. (1)The state remains in the union. (2) The state continues to recognize the constitution (10th Amendment) is the supreme law of the land. (3)The dispute is mediated by the supreme court following it's constitutionally assigned duty to resolve laws that are in conflict with each other and/or the constitution.
