Looks like you have the logic for what you want to do. The only thing you did not covered is when square and size is less then 800 pixels.

If width  == hight  then

   case  width gt 3000 resize to 3000

   case  width  gt 2500 & lt 3000  resize to 2500

   case  width  gt 2000 & lt 2500  resize to 2000

   ...

   case width lt 800 forget about it

else not square forget about it

end else

I had all but the briefest of looks at this and I don't think you can use switch/case like that…? I think 'case' evaluates a variable not an expression… Some one will tell me if Im wrong as normal… You could other wise just chain if/else if… OK had 10 minutes a possible route could be some thing like this using 'case' where you do some math first so case gets a value passed to it… Do check my math thou… I don't see any issue with calling a resize on images that match your value… nothing will happen will it? Oh yeah I was working in pixels as always…

#target photoshop

var doc = app.activeDocument;

var docW = doc.width;
var docH = doc.height;

if (docW == docH && docW > 800) {
     
     switch(Math.floor(docW/500)) {
          
          case 5 : doc.resizeImage(2500,undefined,undefined,ResampleMethod.BICUBICSMOOTHER); break;
          case 4 : doc.resizeImage(2000,undefined,undefined,ResampleMethod.BICUBICSMOOTHER); break;
          case 3 : doc.resizeImage(1500,undefined,undefined,ResampleMethod.BICUBICSMOOTHER); break;
          case 2 : doc.resizeImage(1000,undefined,undefined,ResampleMethod.BICUBICSMOOTHER); break;
          case 1 : doc.resizeImage(800,undefined,undefined,ResampleMethod.BICUBICSMOOTHER); break;
          default : doc.resizeImage(3000,undefined,undefined,ResampleMethod.BICUBICSMOOTHER);
          
     }
     
}
