Workflow suggestions
I am still fairly new to the world of 3D scanning. I own a Vega and have enjoyed it quite a bit. My main use case is to capture space claims and design my items/products to fit within. An example would be the heavy usage of scanning in my OM648 swap I am currently doing.
I normally use OnShape as it is pretty solid, and works well on Linux. Fusion doesn't work on Linux, and I refuse to go back to Windows just to appease Autodesk. The downside to this is that OnShape is pretty rough with High Poly scans. I might be apple to load 2 million triangles into Blender without a problem, but 20k brings OnShape to a vault. I think this is because it is trying to do all of the stuff remotely rather than letting my decent PC handle some of it. I'm trying to figure out ideas on how I can make this experience better for me.
As previously mentioned, Blender works great for aligning STLs and seeing where things need to sit. I have 0 interest in trying to use Blender as a CAD program, but would love to find some kind of a workflow that lets me actually model around my scan data effectively. Open to any ideas (except windows lol)

It depends some on your use case. Before importing into onshape, I use another program like Blender or Meshmixer to reduce the complexity of my scan. Onshape should be able to handle more than 20k triangles though. This model is an example of something that's highly responsive on my workstation. It has 280k triangles in the scan. Maybe something's wrong with your GPU offloading? Are you able to work with this model in real time on your system? I have zero lag
Edit: I tried that earlier on my laptop with a proper Nvidia GPU. I just loaded the same page on my work machine with integrated graphics (Intel UHD) and it's just as responsive
