Pick one and start there
Most people start with one download and add the rest later. The page grows with you instead of needing a rebuild.

Start with one — A single PDF is a real business. Add the course when you're ready.
Mix them freely — A free lead magnet, a $29 guide and a $300 coaching call can live on the same page.
Every type delivers itself — Files download, courses open a player, calls book a slot, communities let people in.
