What if you need more than 2TB of iCloud storage?

I currently have nearly 2 TB of photos and videos in Apple Photos. If I add in the backups of my devices and documents, the total size exceeds the maximum iCloud subscription at 2TB. If I try to subscribe to iCloud, it does not let me. It says I basically have to delete photos and videos from my mac to reduce the file storage below 2 TB. Does anyone else have this issue and what are you doing in this case?
