Newbie help please

I have installed the free version and linked my downloads to a google drive. I would welcome help to achieve the following.

I want to display my downloads in a grid whilst displaying the respective image for the pdf file with an image hover mouse over effect.

I would also like to have categories and tags for the downloads with the ability to select display of downloads by category and tag filter.

Happy to purchase software to achieve this and all advice welcome.

David
