Need Help With Organizing Content – Any Plugins?

Hi! I am hoping someone may help. I am starting a new blog so I can post articles, sermons, papers, etc. regarding ministry. I want to make sure I create the right kind of category system so it is easily searchable by category (articles, sermons, papers, etc.), by a subcategory (Theology, Christology, Eschatology), by Scripture (like a scripture index of scriptres that appear in the writings), and by topic (God, faith, justification, works, etc.

Does anyone know how I can do this? I know how to set up categories, but is there anything else I need? I want people to be able to navigate around easily.

Another ministry web site I have seen that I LOVE is John Piper’s web site, https://www.desiringgod.com where you can search sermons (by date, series, topic, title, occasion, etc), and then do the same for online books, conference messages, etc. It is highly organized and very easily searchable.
