Hi @Kimberly Kindle , welcome to the Atlassian Community and thanks for your post.
To migrate the Confluence cloud site / content to data center, you can follow this guidance, maybe you already found this - https://confluence.atlassian.com/doc/migrate-from-confluence-cloud-to-data-center-298979321.html
As the guide explains, you can either do the whole site or migrate space by space but it depends a bit on your setup. If the data center instance already has some spaces, you might need to do a space by space migration so you don't run into problems with duplicate keys.
Then, in terms of resetting the cloud site, you can just delete the product - https://support.atlassian.com/atlassian-cloud/kb/resetting-your-site-if-you-only-have-one-cloud-product-on-the-instance/ and then re-add it. It depends, again, on what you actually want to achieve. If you want to delete everything and start over, this could be a good option. If you need to keep some things and not others, you are probably looking at a more manual process of going through and removing the stuff you don't want.
Anyway, if you need help, you can always ask here.
I would say though, if you have any budget at all, typically these kind of migrations can be complicated to do without a solution partner. You could approach one in your area, if you want - https://partnerdirectory.atlassian.com/
I appreciate this isn't an option for everyone.
Best wishes
