Some of these types of films are available through Kanopy, which you might be able to use if you have a US library card. If your library participates, it’s free, but limited to 10 movies or episodes per month. It was a great day when I found it, owing to a comment here on HN. Far better catalog than Netflix.
Kanopy is the best! I used to use a service called Juststreamit, to find what streaming service something was on, now there's an app called Justwatch. I'd signed up for a Kanopy account years ago and was able to put it good use. It has so many indie films that I'd been waiting to watch and you can also sort by language which is great for learning.
