Re-read Mike’s post, he says Pal is UFF except for DV. I think all DV (miniDV) is LFF or field 2.
Be careful on MJPEG cards, the field dominance is typically based on the card, so you could capture analog betacam into a Blackmagic card and it is one dominance but do it in a Media 100 system it might be another. You have to get the field dominance from the manufacturer typically.
If you shot progressive (24p or 30p for ex) it is not interlaced so you don’t want to induce fields when you export.
