SharePoint Online 2019 communication website / tabs

I am a librarian and I am responsible for creating a SharePoint website for our college staff and students. The website is SharePoint Online 2019 and a communication site.

Tabs (four) must be inserted within a site page and web parts such as quick links or images must be added. The tabs contain resources for the topic overview, which we cannot accommodate on a site page, as this leads to a too large scrolling.

I am a beginner with minimal programming experience. Can you tell me if this is possible with the type of site I'm working with and the layout I'm trying to create? And how would I do it?

Thank you for any input you offered.
