Default Advice on bath exhaust vent termination.

I wanted to ask your opinion on the duct termination for my 2 bath exhaust fans.

The question I have is for the termination of one of the fans. It would be easier for me to cut through my cedar siding to do a side wall termination. It would be about 12 -15 feet total vent length. If I did the roof I would need to hire someone to vent through the roof(About 3 feet)

The fan is a Broan Model 683 CFM 80

Not sure of the maximum length of vent.

For sidewall application.
Would you slope vent up slightly or run on attic floor?
What type duct would you use? Flex, semi corrigated metal?
