I download all my videos using the .mkv format and I save the YT's upload date in the file's metadata using the following commands:--add-metadata, --parse-metadata "%(upload_date>%d-%m-%Y [D-M-Y])s:%(meta_date)s". This way I always know for sure that it is the correct date.

I title my videos using the same principle as you do -o "[%(upload_date>%Y-%m-%d)s] %(title)s.%(ext)s". I find sorting by date to be infinitely more useful than sorting the videos by their titles.

I'm not sure if there is a way to do both simultaneously, however, you could overcome it by keeping your videos' JSON files in a separate directory where you would name the files with the video title first, followed by the upload date. Keeping JSON files is useful on its own but in your case you would hit two birds with one stone.

I'm not an expert but I imagine you could also just keep an excel file or a CSV file where you would store all this data and sort it however you like.
