It really depends on your focus. A lot of things get classified as VFX that aren’t actually VFX, but I’ll step away from that for now. For actual VFX Definingly Core Compositing and probably Core Physics. If you want to create your own element or add CGI Then the entire CORE course is well worth your time. Geometry node is also something to look into especially if you’re looking to add weather or advance simulation. Some course that can help with that are Assemble and Particles Course. There is also Intro to motion graphics which to be honest I don’t know much about motion graphic beyond Intro credits and End Crawls
