I prefer NGINX with autoindex. Lightweight, no JavaScript, looks like every Linux ISO mirror, filenames already have all the required info, can be quickly searched with CTRL+F, fits perfectly to my laziness.
If you want some improvement, you can use FancyIndex module.
But the files need to be in codecs supported by your browser(s). I prefer AV1+Opus in WebM container which have been supported by Firefox for a while. At this point it’s really only Safari not fully supporting AV1 because it relies on hardware decoding and Apple wants you to buy new hardware.
