Question

How would I accomplish this? Setting a default keyword argument for the field didn't seem to work.

When you tried to set a default keyword, did you set it on the RichTextBlock inside the StreamField? According to the docs, all block types accept the following optional keyword arguments: default, label, group, icon, and template. For example:

body = StreamField([
        ('paragraph', blocks.RichTextBlock(default='Add you content here')),
    ])
