This is my recommendation. A Razor Basilisk V3. I have used the V2 model before, it lasted two years of hard use till the bottom wore through the slider pads and still worked.
I am currently using the latest Alienware mouse, it has held up well, but the matching keyboard has keys popping off, with broken side clips from typing normally lol.
Lots of options out there, but a high resolution wired gaming mouse will yield the best results I would think.
Best upgrade for Fusion 360 is a big 4k or higher resolution monitor, assuming the video card can handle it.
