Complete Beginner taking on a plot

After a nice little harvest last year with a few pepper, chillis, broccoli and loads of courgettes I have decided to take the plunge and go for an allotment plot this year. I am have reading up for the past month and I have a wide variety of seedlings going in my greenhouse.

I am hoping to get the plot within the next month and will be pretty much ready to get stuff in the ground straight away, I am not using raised beds this year that will be a job for next year along with building a shed and maybe a pond I just want to get things planted this year and not worry about the other bits. I am growing everythings broccolis, kale, sprouts, courgette, mangetout, herbs, onions, cabbages, also would like to plant some new potatoes but think I maybe too late for it.

Im looking to put my veg into four sections with grass paths down both sides and through the middle to separate veg beds and to make it easier to navigate round as its a big plot, any advice on how I should plant them i.e rows etc would be great as reading stuff on the interent and watching videos with all the allotment bloggers has just confused me as everyone does it differently so any advice would be great.
