My setup is really basic with three categories: Action based, Audio based, VR.
I sort my videos based on created date (most recent first), which I use to checkout new stuff. Mostly I use shuffle where a random video from the active folder/filter is played.
I create symlinks to the videos from my “main” library, which contains unscripted videos, to the Action/Audio/VR funscript folder whenever I download a script so I can keep both libraries organised without duplicating the actual videos.
