You can probably grow most veg in pots but, in terms of crop size and harvest, some veg does do better in the ground.
Spuds in bags, salad leaves and herbs do well in pots, radish, spring onions, spinach and chad do well in troughs. Dwarf varieties of pea's and beans do well in pots , the taller varieties although they can be grown in pots, grow well in the veg plot and take up little ground space.
Brassicas like broccoli, brussels, cabbage and cauli like to deep root and if you only have one veg bed, take up alot of space and need a long growing season, so are not really suitable for pots or small spaces. Calabrese matures early though. I've always grown it in a veg bed, and, just one or two plants, but it's a good cropper, once the head has been taken off it will produce lots of tiny off shoots, maybe worth a try in a pot.
Roots like beetroot and carrots do well in pots,they mature relatively quickly and can be picked small.
Outdoor bush toms do well in hanging baskets or pots raised off the ground but need to be kept somewhere warm before planting out time.
Stuff in pots needs to be watered regularly and the compost shouldn't be allowed to dry out but kept moist otherwise the veg/herb will bolt or simply dies. Where you are only growing one plant in the pot like toms, a layer of gravel or stones helps to stop the compost from drying out, when it's hot and sunny. I've also put in a layer of gravel for beans and pea's grown in pots.
Blueberries do well in pots too but need the right compost.
