So many Netflix series shot on 16mm film....so what? Maybe Netflix Originals isn't but who cares about resolution... Even if you upscale full HD to UHD no one will tell the difference!
With no hesitation I would go for bmpcc with canon speedbooster. I recently shot this film https://vimeo.com/116101747 just with this camera and I was amazed with the DR versatility, sharpness and many other stuff. Just get a few extra batteries or a solar powered charger like goal zero or something. Camera is super compact and I don't see any reason to shoot 4k. And it also has a timelapse mode so you have some beautiful 1080 DNG files to process.
