Open random file from subfolders, taking into account metadata

I have a batch file which opens a random file from a number of subfolders. I got it from this post: Open random file in a folder (and include exceptions) - in batch

It currently creates a numbered list of files, generates a random number and opens the file that corresponds with that number.

I would like to modify it so the numbered list is a list of files that match a specified metadata query i.e. image height = 1080 for example.

Is there a way I can do this that doesn't take ages every time I open the batch file?
