What is the difference between the various (SharePoint Online) Update type?
In the O365, Set Workflow Status (which is not available in NAC). When using the NAC/NWC Upgrades converts to SPO - Update Items → [Items at root level but ignore folders]
The O365 Update List Items when converted to NAC/NWC becomes SPO - Update Items → [Items and folders at all levels]

Below is what the help documentation says. This might help clear things up.
“Select the Update type to specify what items to update:
Root level but ignore folders: Update items only in the root level of the list.
Root level and include folders: Update items at root level and items in folders.
All levels but ignore folders: Update items in all levels but ignore sub folders.
All levels and folders: Update items in all levels and all folders.”
