I currently have my main Ryzen 3 desktop system running Windows 10 with no VPN and Plex Media Server. I have a Win 7 Guest VM I open each morning that has a VPN active within it that runs Sonarr to grab/download/sort my TV Shows as they air - the Plex on the host refreshes and we can access the content on our devices well. I have some family members also accessing but I don't run the desktop 24/7 as it's in the bedroom - I do video editing, coding and whatever else on it.

Yesterday I thought a solution to the issue and picked up a Mac Mini that I'll run 24/7 and store the media on a USB 3 external drive. I might install Win Server 2008 R2 on it but if I were to continue using OS X what options exist to have Sonarr run in the VPN and grab my shows. Same as Windows host - a virtualbox VM? Are there better options?

The VPN I'm using is Windscribe Pro. I don't use the VPN on the host so my normal browsing/downloading goes unaffected.
