JPEG
Provides the smallest files by a mile, but there is always the chance of artifacts from high compression.
OpenEXR
Supposedly Industrial Light & Magic's 'main image file format'. Oddly the openexr.com website is shockingly janky.
DPX
Based off of the Blackmagic forums alone it appears DPX is a more widely adopted format than OpenEXR and only slightly larger in file size. Also a bitmap format like PNG.
PNG
This old codger has been around for 21 years now. So long in fact that it was originally created as a non-patented replacement for GIF (yes that kind of GIF). Roughly twice the size of both OpenEXR and DPX.
TIFF
Tagged Image File Format (I know, I didn't know that either) is raster based, also known as bitmap. If you are reading this than you are looking at a bitmap. Each pixel on your screen is represented as individual colored squares, stored by a few bits each in your GPU's video memory. Not nearly as big as PSD files but still one hell of a lot larger than JPEG.

PSD
Exporting to photoshop native PSD files takes a 90 fold increase in storage requirement. The only scenario I see PSD worth it is if you planned on doing heavy per frame basis editing with many layers that you could save and reedit at a later time.
