Thats a nice list. Easy enough to cut up into groups as well. Not a selection for classic crop rotation, but nice nonetheless...

Broad beans
Runner beans
Sweetcorn
Courgettes (though plants might take up too much space)
These guys all want a rich soil. Dig in plenty of muck, and remember that they're going to give you a lovely, rich spot for next year. Add a fertiliser like growmore or blood fish and bone a week before sowing too.
If you're going for one crop of broad beans, just sow Aquadulce claudia. You can spread your harvest with a second sowing in, say, February or March.
Loads of varieties of runner beans, they're all pretty good. Currently I favour one called, 'painted lady'.
Sweetcorn... Now, you can make good use of your sweetcorn space (which you need to grow in blocks rather than rows!) by planting squashes around the outside and trailing them in amongst the sweetcorn. Last year I had great success with pumkin 'small sugar' in amongst the sweetcorn. Butternut squashes grow in nearly the same way.
There are so many courgette varieties... I currently rekon that 'parthenon f1' is the most reliable, gives you a crop even in bad weather, but 'green bush' is the usual favourite in a smaller space.
Broccoli (calbrese)
Caulis
Lettuce
Rocket
This isn't a normal selection I've picked out here, but in your rotation it works out fine. Manure the ground in Spring if you can, and I'd have this selection following the first lot above. You might want to check on the soil pH if you can, you want a neutral to basic soil for brassicas. I've included lettuce and rocket in here becuse although they're not fussy in the slightest, they fit in best here, although you can keep sowing them wherever theres a gap and they will thrive.
As for varieties... I don't have a good grasp on different varieties of caulis, I find them all difficult, and although I thought I was good at calabrese it all went pear shaped this year and I got hardly any
I would reccomend broadening things out and having some early purple sprouting broccoli too, as thats at its best in early Spring when you're crying out for greens, and if you can bring yourself to plant some kale too you'll have green stuff all winter (an Italian one called 'cavolo nero' is nicest I think).
Lettuce... See here:

Onions or shallots
garlic
Leeks
fennel
This is what you'd call 'other' and it fits in next. Okay, fennel is technically in the same family as carrots and parsnips, but it wants a richer soil. Only manure lightly, and this is your next rotation. Add a fertiliser like blood fish and bone or growmore too. For onions, garlic and shallots its worth adding something fairly high nitrogen as a mulch later on, so I usually pick up the bags of used coffee from starbucks.
Fennel is fussy, the others are easy. Fennel is best sown late, mine goes in as late as July and is then watered in very well, although next year I'm experimenting with a really early sowing too. Mid spring sowings tend to run to seed.
Parsnips
Carrots
Beetroot
Good old roots section
Last rotation, give it some growmore, no manure at all.
Carrots - I've listed some varieties already, but check out the main crop varieties like 'autumn king' too, they sit in the soil all winter, which is handy. I also like 'danvers half long', 'early nantes', 'chantenay', and many others. I've got a thing for different carrot varieties!
For fun, try one of the multi-coloured variety packs you can get from many of the big companies now. You get white, purple, orange, yellow... Look great on the plate.
For parsnips, theres a lot to be said for the classics; 'tender and true' and 'the student' are good.
Beetroot... Would like a slightly richer soil, but it'll do fine in this rotation. The classic varieties ('detroit globe', 'boltardy') are good, but check out some of the others too. I adore 'chioggia', which is red and white striped when cut through, and some of the yellow and white varieties are fun too. Monogerm varieties (with one plant per seed rather than four) are easier (so varieties like 'moneta'), but not as nice. Take your pick. While you're growing beetroot, I can't reccomend swiss chard (almost the same plant but you eat the leaves and stems) highly enough. Try 'bright lights', a mix of many of the better coloured varieties. Then you can pick out the ones you like and concentrate on those in future years.
If you've got space left in this roation,
do try salsify or scorzonera. Much underrated vegetables.
