Not an expert by any means but I’d imagine focusing on the key results, outcomes and insights, and telling a story about how you got there. I’m struggling with something similar, where I have an especially personal investment in the visual presentation of a ~30 page report publication. I think it becomes more compelling if the context of the research and publication are presented. Save yourself the headache later and be especially clear of what role you played, how you contributed, if it was decisive, etcetera. And of course, share with us and get better feedback as you figure it out!
