Still fuzzy on Linear workflows

So I’ve rendered my Blender project as an open exr. I’ve got a composite going on. Some of the colors I’ve noticed are above the 1.0 threshold.

Should I just use RGB curves until I bump the problem areas down to 1.0? Or should I be using the tone map node instead? Or should I just render out the movie and let the codec decide what stays or goes?

I feel like if I just render it, it shouldn’t be that bad. Most of the colors that are 1.0 or above are glares of light anyway.

What sort of flow from Render to Composite do you use? Do you color correct?
