Rating that many images is not going to be enjoyable. Even with the nice tools kindly suggested here. If it was not done in the last 6 years it is not urgent.
Instead, wait a bit more for AI to catch up. In a few years there will be tools to do just that. I guess they will cull 2/3 of the load out of the box, and you will guide it a bit over a few dozen images so it gets you the top 10%. Do that last part yourself, image by image.
Don't do it. Hear me out.
