For my case, I straight-up used it as a texture in a Sprite node. However, my little knowledge on vector art ends up causing my youtube videos to load much slower whenever I open a project involving vectors. Just recently, I've learnt to optimize svg.
While Godot has nanoscg for rendering vector art, it's apparently intended for small icons. Other takes on rendering vector art have come and go.
For now, the best way to use vector graphics is to export them as png instead.
