Error signing large Adobe Sign documents

I currently have Adobe Pro licenses and need to sign two files that are over 100 pages and 10MB in size.
I have already seen the limits with the different licenses, but I need to know if there is any other option to sign these documents.
We are talking about files of: 349 pages and 42MB, and another file of 206 pages and 7MB.

Is there any solution to be able to sign those documents, even if it implies a change of license?
Thank you very much.
