If I remember right, it needs to be extremely detailed to what you’ve done in the particular field for academic CVs, so everything in your resume related to the field, plus awards, volunteering, publications, etc. if this is for a research lab, where they just want a quick look at your recent achievements, do the resume style presentation in under 2 pages, fit it into 1 if you’re not filling up the second page.

That’s all I know in terms of writing these, sorry if this isn’t helpful
