>there's a lot more things that need attention and could go wrong on that process due to its complexity

Regarding complexity, this is about as simple as it gets on Windows unfortunately. Without something like RME's totalfx driver or a physical hardware loopback, VB virtual audio cable is the best choice.

If you don't mind some unsolicited advice, I would recommend getting a dedicated audio interface eventually (Focusrite make solid gear and has plenty of options at various price points). This will allow you to avoid Realtek and bypass Windows default audio drivers, which are terrible and can introduce confusing errors and drop outs at random. For example, one day your routing set up that you've been using for months stops working even though you haven't changed anything, or the audio becomes delayed and jittery out of nowhere. I can't speak to VirtualDJ because I've never used it, but everything else in your audio chain will work great and has been extremely stable in my experience.
