I understand the sweet spot is between 400-1200. However, is there a problem with exposing for 800 them changing the iso value to something lower in post? Thanks

No problem as long as you exposed correctly in the first place. ISO is metadata on Red cameras.

Doing what you say is actually a really good thing.
The goal is to give the sensor as much light as possible without clipping parts of the scene that are important, so you want to lose ND to maintain a stop, or open up if you have to. You can always add noise, or grain, or stop down using FLUT in post, but you can never put that information back.
Imagine you are shooting at asa 800, but you can over expose by a stop and a bit before clip. Then you've got an 'over exposed' image at 800, but if you then visualised the data at 320 and it's a balanced exposure, you can see how it's going to look in post, right there on set while you're shooting it. Don't be afraid to play with the metadata while you're on set.
Apologies if this is too elementary.
