Yeah, importing large numbers of files can get pretty frustrating when things don’t auto-associate correctly. I ran into that with a sample library last year, tons of audio and notation files that I hoped would just line up based on name. Even with matching file names and folders tidy, some of them wouldn't sync properly. Ended up having to manually link a few dozen of them. Not ideal when you're dealing with hundreds.
Whenever I work on editing videos or syncing music with visuals, especially outside of iOS tools, I’ve looked into iMovie-like options that are easier to manage on Windows. Found a few that helped, especially this one from https://www.movavi.com/imovie-for-windows/ I came across while digging into iMovie alternatives for Windows. Pretty user-friendly and good with media syncing.
