Is there a way to change the related list title to something other than FTP Attachments on standard objects? I was able to change for custom objects

Ans: No you cannot rename the related list of FTP Attachments® for standard objects but that can be definitely done for custom object as follows:

To rename related lists resulting from a custom relationship , we will need to locate the custom relationship field on the child object:

1. If the child object is a custom object: From Setup, go to Create > Objects > (Name of Object).

    If the child object is a standard object: From Setup, go to Customize > (Name of Object) > fields.

2. Locate the custom lookup or master-detail field referencing the parent object.

3. Click the "Edit" link next to the relationship field.

4. Rename the "Related List Label".

5. Remember to "Save" when finished.
