RTO for sales folks doesn't make sense to me either. Typically you want your sales folks on the road not in your office. I think sales is a good candidate for fully remote.
Most roles can be hybrid/remote. Regardless of Tech, Finance, Marketing, whatever, if the job involves sitting in front of a computer or being on the phone all day it's a good candidate. If you were doing the job remotely from March 2020 through the end of 2021 and being effective, it's a good candidate.
