Thanks guys, photoJPG seems to hit a sweet spot between quality and size, or PNG if I need an alpha. Cut the upload from 1.8 gigs to 350 MB. PS Has anyone worked with Arri Alexa footage? I think either the person who did the exports to prores screwed up the compression / color space, or they may have underexposed their whole shoot. There is very little dynamic range and everything looks super flat. Is it possible to check the color space of a specific clip? I don't see it in any of the metadata. Or do I need to do a color space conversion in AE for the Alexa that I'm missing? My gut tells me it was the DP's fault and not the trip to prores.

As for exports, would it be better to add in some 32 bpc curves to expand the DR, and export this "corrected" version? It looks much better and is much easier to work with. Or should I just use that on an adjustment layer, and color correct the effects plates to the neutral footage?

The Avid codecs are free, cross platform, and support alpha.  They take a bit of work to get right, due to the menu options, and that frame size & rate matter.  They work OK with FCP, but not ideal.

Your best bet is ProRes.  If you're on Windows, I've read there is a way to encode, but it requires some hoop jumping.  Google might present the elixir.

For photo-real images, the files are half the size of Animation; it has an alpha channel; and it's nigh-universal (installed with standard QuickTime). The performance leaves something to be desired, but that's OK for my purposes.
