Require an advanced citing or referencing method

Hi, I am trying to create a scientific / legal blog. The regular blog features don’t work for me.

What I need is a way to create a page that has advanced citation capabilities such as end/footnotes which can reference links, exhibits, documents, pictures, books, etc.

For example, A first sentence might reference a specific page in a legal case. The next sentence may reference a pdf document that I have in a side bar. The next sentence references a link to 3 different websites in support of the statement. The next sentence references a specific area of a map which is underneath this paragraph. Another sentence references a specific time code of a video either I link to or embedded in a sidebar.

I haven’t been able to find something that really fits this. Even Google scholar is not well developed. I would also like a bibliography/endnotes which show all the citations if possible.

Zotpress, Modern footnotes, etc don’t seem to have enough functionality. Please LMK if you have suggestions. I would prefer either a free plugin or a lifetime plugin or bundle. Please advise. Thanks.
