The basic needs should be: Kernel with real time scheduler, X11 server for display unless it is run remotely, linuxcnc. I guess some more would be needed to get it started but not very much.
Usually there are plenty of space on harddrive so any ordinary distrubution could be used with out any real drawback. Only reason I could find to use simplest possible would be for cheap mass produced devices. I have however discovered an STM32F407 ran a control loop perfectly with a frequency of 40kHz with around 30% CPU load but with an old ordinary higher clock frequency computer I can't run at 1kHz reliable. Modern GOOD for real time system micro controllers usually have nested interrupt controller with priority but I do not know if this is possible on an ordinary computer. I guess effort could be best spent on kernel and in particular possibility to reduce priority of interrupts for ordinary tasks like disk I/O, graphics, other non real time I/O or non real time interrupts. Then clock cycles at "high" priority are free to use for real time tasks I expect good real time performance will come almost by itself.
