The older Spatial Allocator surrogate creation tools have some trouble with larger data and I don’t believe they support the geopackage format.
You can try the newer SurrogateToolsDB which handle larger datasets better.
Since your weight file is larger than 2 GB and can’t be stored in a Shapefile, you might research how to load the data into PostGIS.
But once it is in there, I think the newer surrogate tools should work. If not, please write again.
