I pay for iCloud 2TB by itself right now. What happens to my existing iCloud 2TB plan, if I sign up for the Apple One Family plan that only offers 200GB of iCloud? What would I pay in the end to have the One Family plan and the 2TB plan of iCloud+?
See the information in What happens to your iCloud storage when you sign up for Apple One - Apple Support including the following:
If the iCloud storage included in Apple One is less than your current plan
You keep both your current iCloud+ plan and the iCloud storage in Apple One.
If you prefer to keep only the storage included in your Apple One subscription, you can downgrade or cancel your current iCloud+ plan.
