Author Box Grid

Hello,

I'm in the process of rebuilding our site on Generate Press and Elementor. My last theme had a custom post type built into the theme for authors. This created an author page as well as a author box "grid" (vs. a singular Author Box)... We were using this function for over 400 Contributors (Authors) and "Team Member" bio on the website.

(example) http://www.trailsisters.net/contributors <-public website still on old theme.

I think that we can create a custom post type, and use the ACF plugin to great Custom Fields and a template for pages but I'm a little stuck on how to build an Author Box Grid (using Elementor?) that would eliminate the need to create over a couple hundred Author Boxes manually.

If there is are any ideas from the Generate Press team it would be greatly appreciated. I thought I would ask here in addition to on the Elementor forums. Also, I'm open to not using Elementor if there is a better way.
