Supporting SAAS free trials

I'm interested to understand different ways companies handle free trials.  We're trialling  (excuse the pun) them as a method of accelerating sales but to support them in the long run I don't know the best structure between CSMs and Sales to support the trials.  I have a lot of questions around support/ownership (dedicated role which mixes CSM/Sales skills and responsibilities?), qualification for a "good fit", playbook differences to standard customer onboarding, compensation if conversion, and more.  I couldn't find any results when I searched for "trial" here but I know many of your companies must do them.  I'd be grateful to hear from your experiences.
