"3-4 hours of good sun" is not much. I presume this is the maximum summer sun? Fruit trees won't fruit much with less than minimum 6 hours full sun.
Having said that, most soft fruits can handle less.
I know nothing about roots and sewers, so I'll leave that one alone!
Is the ash a must-keep? You might have to get rather pragmatic if you want to grow a major part of your diet...

choose the fruit that is best suited to your zone (check catalogs) and that is best suited to your diet..something you love to eat.
There I go, hinting again ; ). By soft fruit, I mean raspberries, currants and gooseberries, among others.
Be aware that I'm not taking your climate into account...
I think sun , or lack of, is a real issue if you want apples or other 'conventional' fruit, and you might need to consider unusual fruit or options for improving your sun.
has anyone had any luck with 3-in-1 trees?
