Text & images are indeed no problem.
We also support a range of embeds, like YouTube — let us know if there's something you'd like us to support.
We have an embed for code, though I'm not sure if it could be run directly from the web page.
I just noticed we don't support PDF's. For now, it's possible to make that work via a Google Drive link or similar approach. But this is great feedback, will take it back to the team.
Let us know any other feedback, or if we can help you get set-up on Paragraph!
