Something exciting has happened recently. AWS has released the design system that they now use for the AWS Console as open-source! The name for the design system in CloudScape and it is as beautiful as it is functional.

Find CloudScape here: https://cloudscape.design/

You can integrate it with NextJS but you may run into some some problems, so I wrote a blog post about it:

I hope it helps! Enjoy CloudScape!
