Here is an example:
I could book a 30-minute service at 9 AM or 50-minute service at 9 AM. Is there an app that gives my customer the ability to book a 50-minute service with me that would prevent someone else from booking a 30-minute service with me at the same time? I’d also like the customers to be able to reschedule their own appointments.
Thank you for your recommendations — I’ve looked at Sesami and BookThatApp. But I’m not sure if either of them will meet my needs. Do I need to use Acuity or Calendly in conjunction with Shopify app BookedUp?

You don't need another App.
To set this up in BookThatApp (https://apps.shopify.com/bookthatapp)
This important part here is the capacity. Since it is based on the product level it counts bookings for any of the variants for that product. In other words, it will prevent a booking coming in for the 30 minute variant if there is already a booking for the 30 or 50 minute time slots.
Please note that BookThatApp also supports setting capacity based on Resources (e.g. staff members). Please see our help desk article for more info about manage capacity.
