To be clear, the option to wipe the SD in TWRP just formats the "virtual SD" (user accessible) partition. You should definitely also wipe Data (factory reset) as that is where most of your personal info is stored. For that matter, wipe everything in the Advanced Wipe options of TWRP, to be safe. I think that is what Madcat8686 meant above when he said "full wipe", but he wasn't explicit, either.
