Run Adobe Illustrator on Surface Pro X

Surface Pro X include ARM CPU, not Intel CPU.
Surface Pro X can only emulate x86 applications.
Illustrator 2020 cannot be used because it becomes a 64-bit application.
Illustrator 2019 can be used because it is a 32-bit application, but since it is emulation only, Adobe will not guarantee operation.
Since 2019 will not be available in the future, it is likely that the results will be unpredictable.

I have the Surface Pro X . It does surprisingly well for a lot of tasks. Connect it to a screen and keyboard and it feels like a full size computer. However, Blender will push it to its limits very easily. Illustrator , works just fine, but it's not very smooth for more complex projects. I don't know Fusion.

The touch pen is ok for taking notes, I haven't really spent much time drawing with it yet. The few times I did, it was the software that felt the most limiting. I haven't really found a drawing program that works for my purposes yet. I used to have an XP-Pen Artist 12 Pro display drawing tablet and I believe Artist 12 Pro is much better for drawing.

I use headphones and the mobile mouse on the go. Its a really nice elegant compact computer that won't take up much space in your backpack, and I really enjoy using it. But for heavy computing tasks you may want a more powerful machine, dedicated GPU, a more stable clamshell design and a larger screen.

I don't use a USB dongle on the go, but I use the surface dock at home to connect all the peripherals.
