Extremely general question. What do you ultimately want it to look like.
You are shooting daylight film so you shouldn't need any color correction filter.
Plus you can correct or add color, or not, later. Whatever you do don't over think your filter situation or your sunset will sink fast. I would just shoot without any filter and have an HMI standing by for any close ups or coverage you don't get in your "magic hour".
I use tungsten film with an 81ef for these situations, but I like to have a bluer-grey look.
Thanks Todd! I am extremely new to all of this, in fact, this is actually for my first project in which I will be shooting with film. Generally, I was hoping to bring out more red-orange than anything since I will have no control over this in post! Thanks for your input, any further advice you have would be appreciated as well.
