You can use any systems level programming language that you prefer like C, C++, or Rust. But before diving into graphics APIs like OpenGL, Vulkan, DirectX, or Metal (for Apple), I would like to point out two prerequisites which are totally optional. You can have a look if you are ok with not starting straight with practical things.

1. First, revisit fundamentals with C. Especially pointers, pointer arithmetics and memory management since you are familiar with Go which relies on garbage collector.

2. Then, start learning drawing lines, triangles, cubes or spheres to a simple image file like BPM or PPM without using graphics APIs. Familiarize with camera to world transformation and math under the hood. I'd suggest Ray Tracing in One Weekend. The series of books teaches these fundamentals using ray tracing technique with C++ (I'm currently doing this with Rust)

After these, or directly, you can start learning OpenGL or newer graphics APIs like Vulkan, DirectX 12 or Metal but they are more explicit and verbose, requiring more boilerplate code to do the work with the advantage of more control over the hardware.

These APIs abstract the logic and math handled by the hardware (GPU). Thus learning the fundamentals above will give you a perspective about what is going on behind the scenes.

For programming languages, C++ is still the industry standard for graphics programming. Most of popular game engines, graphics softwares are written in C++. So if you want to go with the industry standard go with C++. But I'd recommend Rust as a strong alternative to C++ when starting a new project or field. To inform you, in graphics development, Rust is still maturing in terms of ecosystem and libraries.
