How to Best Create Separate Subscribers and User Experience

I use a Bluehost (hosted) version of Wordpress 5.5.1 with Genesis for my blog (recipe and faith posts). I use the Mailchimp service for my email subscribers. I want to create a separate community (faith for caregivers) within my blog where users can subscribe and see posts only related to that community. Is this possible? What is the best way to do this? Subdirectory? Subdomain? Or can I accomplish this with just a separate page? I am not highly technical and looking for the easy method possible.
