You can use the majority of "AI" things with non-Nvidia hardware, so don't feel boxed in by that. Some projects just skew towards the Nvidia tool chain, but there are many ways to run it on AMD if you feel the need.
The "Super" board is just an Orin Nano with the power profiles unlocked. There is literally no difference except the software, and if you bootstrap an Orin Nano with the latest Nvidia packages, they perform the same. At about 67 TOPS.
For your project, you could run that on pretty much any kind of CPU or GPU. I wouldn't pay $250 for the Super devkit when you get a cheaper GPU to do this, and CPU would work just a bit slower.
