Like you, we took over a large garden and wanted a veg plot. I don't know what your budget is, but we opted for raised beds surrounded by gravel (which obviously costs more to set up than just digging a bed).
I love my raised beds and find it keeps the veg and fruit area accessible in all weathers. I never dig it, just fork over lightly witha hand-fork. We have some beds with fixed crops (soft fruit, rhubarb, asparagus) and the rest of the space is used in rotation for all the other veg. Asparagus and carrots do particularly well in raised beds; brassicas don't do so well as they like firm soil.
Do remember to build yourself a big compost bay with two or more sections, as you'll be producing masses of useable waste in a big garden, and your veg will love the results.
