I believe Premiere is very popular for mid-range stuff, but it's not really the "industry standard". If that was anything, I think it'd probably be Avid Media Composer. Linux has (freemium / non-Free) Davinci Resolve, which is increasingly popular in the mid range, across all the main platforms. Edit: The multimedia things I find really painfully missing in Linux are Izotope RX9 and Kontakt.
