@teadrinker couple of other factors to consider in what to grow - may come back and edit more in! -

If you still do your shopping by steam-battle-tank, that is to say, a "heavy" vehicle, roots, squashes and other bulky and dense but cheap veg can be more of a storage issue than a transport one. But if you've gone over to #micromobilty, eg. an #eBike or #cargoBike, #growYourOwn starts to look more attractive. I avoided growing potatoes till I got lobbied into it, but now - as an added bonus - I find flavour and digestibility* so much better I'm not looking back. Especially as they almost grow and to some extent store themselves if you have the space / climate / soil.

Tree fruit, apart from the land use issue, is the years of lead time till decent crops. I'm on my knees by dozens of figs / citrus / nut etc propagations I've made, encouraging them to scale-up production |;-/. There's shading and other issues on the land here that make tree crops ideal - deep roots and reaching out of the shade. Otherwise, I'd happily hand some spots back to the bracken.

*left in well drained soil / stored in complete DARK, so low irritant #solanine compared to shop potatoes often left exposed
