I'd consider revisiting this. These days you can do studio level video production, graphics and pro audio on Linux using native commercial software from a bare install on modern distributions.

I do pro audio on Linux, my commercial DAWs, VSTs, etc are all Linux-native these days. I don't have to think about anything sound-wise because Pipewire handles it all automatically. IMO, Linux has arrived when it comes to this niche recently, five years ago I'd have to fuck around with JACK, install/compile a realtime kernel and wouldn't have as many DAWs & VSTs available.

Similarly, I have a friend in video production and VFX whose studio uses Linux everywhere. Blender, DaVinci Resolve, etc make that easy.

There is a lack of options when it comes to pro illustration and raster graphics. The Adobe suite reigns supreme there.
