With Hyperthreading enabled, you currently have 4 hard NUMA nodes with 10 physical cores and 20 logical cores each. On SQL Server 2012 and 2014 you will have 4 matching soft NUMA nodes with 20 logical cores each.
Upon upgrading to SQL Server 2016 or higher, auto soft NUMA will automatically kick in. You'll now have 2 soft NUMA nodes per hard NUMA node for a ...

With SQL 2016 or later this would be much easier as you could:
Use the STRING_SPLIT() table valued function to pull apart the string
Call that via CROSS APPLY as illustrated in the examples in the documentation linked in "1"
Join to your lookup table
Use STRING_AGG() (or the FOR XML PATH hack you are already using, of course) to put it back together
