Living in a Josephite civil marriage my wife and I would encounter no problems receiving the sacraments. But I'm not confirmed and would not be unless it was wholly within the purview of the FSSP, etc.
Not finding any reference for that in canon law

I might be mistaken because of the chaste relationship. I think of the parents of St. Therese of Lisseux.

Josephite civil marriage? I don’t think there is such a thing. For it to be a Josephite marriage it needs to be a licit, valid Catholic marriage. I think you also need permission of the bishop in that case as well.
