I would argue that finding a chapter on an already civilised world is rather dull (not ncf, but just plain stupid). No doubt Astartes are a great resource, but a whole civilised world is likely to produce all kinds of resources and is that way already a valuable asset for the Imperium. I also believe that harsh coditions likely grow a much more resilient and better stock for Astartes to recruit from, so feudal, feral and death worlds are no-brainers for that purpose. However, a feudal world might just as well develope into a civilised one during the millennia that a chapter might be ruling it... especially if there are resources required to do so.

If you were thinking about something like Ultramar Auxilia, don't. Ultramar Auxilia is the only sector-defense-force I know, it is so completely different to any other pdf I would not even call it pdf. But sure, if the planet is ruled by chapter, and it has pdf, then it obviously is commanded by that world's governor, which is the chapter. However, they do not go and stride on to stars with the chapter, their purpose is the defense of their world. They can't do it very well while sipping tea on Cadian Gate now can they?
