Hi and welcome to the Forum.
For your Workstation you could use either Core or Lite as that PC looks well specified.
The size of HD (SSD) space for Tablet PC is not clear from your post. Websearch indicates it should have 256Gb 0r 1Tb SSD.

That then should be able to run either Core (gnome) or Lite (xfce) editions.
I am not sure if you may have issues with linux kernel support for the Intel Kaby Lake architecture on that Tablet. I noticed some questions re Ubuntu 22.04 (Z17 base) and Kaby Lake during websearch.
