Hello @Jenn Bowerman !
Welcome to Microsoft Qna!
For your case my suggestion is to utilize MS SharePoint
SharePoint and One Drive are quite common and interconnected

SharePoint is easier to use , and the user experience as well is better
Also look at this thread :
https://learn.microsoft.com/en-us/answers/questions/89285/sharepoint-create-document-repository
You will see that it is the best tool for Document Sharing and Collaboration wit a lot of features and add ons that make the experience quite amazing !
You can always use both for advanced flexibility !
