If it was me, I'd buy a 6TB drive for the data drive. Unless you are planning on adding 8TB drives in the future, getting a 8TB drive for parity or data would be a waste.
My setup with what you have would be 6TB parity 6TB data drive + 1TB data drive = 7TB total storage. Then you can buy additional drives up to 6TB in size for your data drives when adding storage to the array.
