Try this

void processCmd(String thing)
{
  Serial.println("In processCmd thing is : ");
  Serial.print(">>");
  Serial.print(thing);
  Serial.println("<<");
  
  Serial.println("processCmd is " + thing);//test if made it here so far
  if (thing == "X")
  {
    Serial.println("Made it this far");//test if thing = X. No idea why this does not work, logically it looks OK.
  }
}

The output is :

ParseCom - The Command is :X

In processCmd thing is : 
>>X
<<
processCmd is X

1234
1257
The Command is :X

Finished

Note what is printed for the value of thing.
Does it equal "X" ?
