Hi all. I have some questions regarding the clinical data model.

• Care Plan: I understand that there is a difference between the EHR and the FHIR-aligned clinical data model - The former has a set of customized managed objects with EhrCarePlan__c being the one at the center of the Care Plan structure, while the latter leverages Cases with a Care Plan record type. If my understanding so far is correct, the question is: Should I use the former when I have data coming exclusively from integration with EHR, or should I consider as best practice that this is a legacy data model and all new implementations should follow the FHIR-aligned one?
• Leads: What is the difference between a CandidatePatient__c record and a Lead record in the model?
• Do you believe it's possible to use the clinical data model side by side with stock service and sales cloud in the same org provided that you properly map record types and processes (specially for cases, leads and tasks? Or would it be wiser to have them in separate orgs?

Any clarification will be deeply appreciated!
