Hi Nicole
I have only just started using Netflix so I may not be able to answer your question directly, but I have been watching films etc in their original language but with Portuguese subtitles which is helping me to learn how things might be phrased in Portuguese. I have tried watching with films dubbed in Portuguese but so far it seems to be just Brazilian Portuguese and I really want to work on my european pronunciation.
When you start to watch something, if you look on the floating bar at the bottom of your screen, on the left is a square shaped speech bubble. Here you can turn on dubbing and subtitles and choose which languages you want.
I live in Portugal now but before moving here from the UK, I used to watch programmes on the RTP.pt website. I could watch some programmes live (but not all due to licensing laws) but also past episodes of soaps,documentaries etc on the RTP player tab. I have no idea if this will work in America. There is also the TVI channel https://tviplayer.iol.pt/
All the best
