Masses: Valid, but illicit. You can attend guilt free if you want to attend the EF and there is no diocesan EF around.
Baptisms: Valid.
Holy Orders: Valid, but illicit. As soon as one is ordained a priest in the SSPX they are auto-suspended and have zero faculties in the universal Church.
Confessions: Invalid, unless you’re about to die. Priests need faculties to hear valid confessions, and as stated above the SSPX have had their faculties universally removed.
Marriages: Invalid. Same as confessions, faculties required.
Anointing of the Sick/Last Rites: If someone is about to die, valid. Otherwise, not valid.
