I usually give file names a human readable name like “report on the event 27.7.1994”. Makes it easier for other people to understand if I need to pass the file on.
For images I keep the original file name when I store it in a database (Capture one/Lightroom/etc) in folders by the year and then month they are taken: 2023 --> 08 and so on. If I eksport images for a specific project, I will keep the original file name but add project name and give it a number based on sequence. Everything else is in the metadata
