Type C. Hmmm.... analog composite. Just out of curiosity, Sony or Ampex... or... Hitachi?

That you have a 10-bit uncompressed file is probably wasted space, considering the original.

It would just be my approach, but... first impulse would have been to digitize ProRes4:2:2 uprez to 1080 on intake. Also, was the original anamorphic and/or is there a 4:3/16:9 aspect letter/pillarbox issue as well?
Your 709/601 and frame dominance issues would go away, but now you are going to have to deal with them. Usually software scaling is not that fabulous. By any chance is there 2:3 cadence involved? (Is the original project film-based (24fps) or original 29.97?)

1080P29.97 is going to require you to do a very high quality de-interlace if you don't want a lot of motion artifacts. And if there was 2:3, then about half your events are going to occur on field 2. Which, I'm not sure you can do in Resolve.... ??? We used to have a ":" button in Renaissance to deal with that.

But getting to scalars, which is almost a non-issue compared to everything else, 64-940 / 0-1023 is probably irrelevant, since the project was never RGB and is now broadcast scale whether you like it or not... and was the 'setup 7.5 IRE' taken out? You should be grading in its native scale. I really don't understand the compulsion to try to push things into xeno-space and then flail around re-calibrating and compensating for the dislocation. << I would like to do this project in French for English delivery, even though it originated in Spanish, so now I need to translate it three ways....>>> because.....????
