I'm new to cockroachdb and I notice that there are several go client libraries

I’m looking to start using Cockroachdb with my go lang micro service development. I noticed that there are several go client libraries currently being offered. Has anyone performed any performance evaluations on the libraries currently offered? I’m targeting a Kuberenetes large scale deployment across many clusters, and or physical locations. Thank you for your time in reading this.

P.S. I have installed cockroachDB and running it currently in docker-desktop and it’s native sql aspects seem incredibly nice coming from a long history with SQL. I’m used to doing mostly redis, mongodb etc lately. We do a lot of POC’s for high profile customers and I really don’t want to present mongodb or redis. I would rather use something like Cassandar, Postgress, or Cockroachdb. Thanks!
