Podcast library and themes

Hi. I’m going to start a subscriber platform mainly to access podcast episodes. I’m not good at coding, and my impression with Ghost is that it is fairly simple to use any of their themes and just add content if you don’t need to customize it. Is my only option to go with one of the “podcast themes”, or could I go with another theme and still be able to organize podcast episodes? There will be quite a lot of podcast episodes as time goes by, and I’m in need of a theme that are good at organizing the many episodes so that it is easy for the subscriber to browse the episodes by theme.
Greatly appreciate your suggestions and advice.
