There are probably many thousands of plugins and scripts available for Gimp. Scattered all over the internet. I don't think it would be possible to compile a list of all of them. A good starting point would be Gimp's built in filters and G'MIC. Getting to know all of these will take a long time.
Another way is if you have a particular need ask here if there is a plugin that can do what you want.
