Matt Russell (above) is the CEO at WHB so I would echo his recommendation of CentOS 6.2 LAMP (Linux, Apache, MySQL & PHP). Additionally, it's my understanding that CentOS is required by cPanel so if that's a requirement, so is CentOS. From your horrid list, 6.2 appears to be the latest and greatest (stable) version so all the more reason to listen to Matt.
I'm currently using CENTOS 6.3 x86_64 so that's another vote for the best CentOS you're being offered. Saying that, of course, you should check Matt's offerings at WebHostingBuzz as that's where I'm getting the 6.3 version. NOTE: From everything I've seen, WHB only uses stable versions of the daemons so, while they are on the cutting edge, WHM is definitely not on the "bleeding edge."
