New to the Magento world. I need resources and suggestions

Hey Starting off my new side project based on magento, pretty new to this so I need some resources to get better quick and some suggestions/tips/tricks. The project is a online e-bike shop I’ll start with a few bikes then scale it up. The setup is AWS + Magento 2.3 x still developing/poking around so no link.

1. Analytics what do I use? How do I implement Google Analytics into it?
2. SEO – what do I need to implement schema rich snippets
3. Any marketing related resources are welcome

Thanks a lot.
