Online Yoga Class WordPress Site

I'm looking to create a warm and inviting WordPress website for my online yoga classes.

Key features:
- Calendar: Displays class schedule.
- Class Details: Info available on click.
- Online Booking: Select, pay, and join.
- Reminders: Class links and reminders sent.
- Session Archive: Recorded sessions, free and paid videos.

I would like your suggestions on the following:
- Ideal WordPress theme for a warm and inviting feel.
- Necessary plugins for functionality.
- Any additional features to enhance user experience.

Please share your ideas and any extra efforts you can contribute to ensure the success of this project.
