I can tell you what *I do*, even if most people don't like it. It does 
makes board up to my standards:

1) I route manualy only the part that I want with wide tracks, usualy a 
contour and a few connectors.
2) then there is a problem: the autorouter does not use that track very 
well (not only kicad's, most don't, don't know about freeroute), so I 
have to connect manualy most ground pins with thin tracks to the wide track
3) then the autoroute usualy runs smoothly
