Plex, that's a good idea. I tried it on my QNAP NAS and the connector is too old to be useful (couldn't get https to work reliably and opening a port to the outside world just wouldn't work). What are you streaming from?

Plex also automatically backs up my family's photos to the server so we dont have to use just google cloud.. though I use both google cloud and plex. (I wanted the full res copies of my photos and videos without google scaling) I should also mention emby works well and I have friends on that side of the camp who are very happy if you dont want to use plex on philosophical reasons.
