The free version is stripped down in the following ways:

Nope - and that's why it's faster! The results are more comparable to lidar (where you're interested in the general structure of a scene/object via point clouds).

Scene Scanner outputs dense colored point clouds. This is different from a mesh but can still be edited and rendered with Eevee/Cycles. The use case is slightly different from photogrammetry, but you can of course still treat them like objects.

Nvidia GPUs only (30xx or 40xx NOT 50xx Blackwell)! The more VRAM the better ;)

Large datasets (with a large/giant quality) can be super heavy on the GPU - more VRAM is always better. Try decreasing the FPS (less images), the resolution, and the model quality.

Unfortunately no - requirements are Windows (x64/86) with an Nvidia GPU (30xx or 40xx NOT 50xx Blackwell)

Scene Scanner comes pre-packaged with the Small and Medium models (Apache 2.0 from Depth Anything 3) - there is also an option to download the Large and Giant models (check the license for commercial use).
