When you create a document, and save it (file / save), it will save in the native affinity publisher format of .afpub. When you export a document (file / export) you will have options as to what format you want to export it in including pdf. So create a document, add your content, export a document in a format that meets your needs. If you go to open new document and you select the different presets, such as print, devices, web etc, you will see that the settings such as dpi and document size change, this is providing you with a basic setup to work with, which is very handy for those of us who aren't experienced with this stuff. It provides a starting point but you can set it up however you personally want it.

I have to say I would love to see a pdf manual available for publisher, but as this is still in beta, I imagine they have other things to do. I came across this tutorial on you tube and found it extremely helpful, not sure if we are allowed to post those links here, but feel sharing is a good thing. I feel it may have a lot of the information you are looking for. https://www.youtube.com/watch?v=wDfq4zOmmKk

Thank you very much, for both the brushes and the tutorial.
