I see now. As far as I now there isn’t a shortcut solution like you want. Though I do believe that Windows and Linux allow you to sort files by metadata like genre. Not sure about Android.

Why not host Jellyfin? Or point your OSs media player to the folder? You would be able to sort any way you please.

Lol. It actually gives me anxiety thinking about a single folder with hundreds of video files just sitting there unorganized. /shudders

Create an NFS share and mount it on your Linux machines and create a CIFS or SAMBA share and mount it as a drive or network location on Windows.
