I understand what you're looking for. This RoadTracker also would reduce my current task effort to probably half!!! It would be wonderfull to have somthing like that in QGIS, for example.

comment How to find most common classification within buffers?
well, when you intersected the buffer withe the classification layer, the result was a shapefile, right? now go to file explorer, find the shapefile and open the correspondent dbf file with excel. then try pivot table to analyse the data.
