Hi and welcome to the forum
I would suggest you try a few things so you experience a variety of growing methods :
Early potatoes as they usually miss any blight and taste brilliant when freshly dug
Some onion sets and some leeks
Climbing beans of some sort - runner beans or french beans, whichever you like most
A couple of root crops like beetroots or carrots
If you like greens, chard or perpetual spinach are easy and go on for months
Sweetcorn - fresh picked is nothing like shop bought
Squash or pumpkin, just because producing a big show off veggie like that really makes you feel like a successful grower
I'm sure you will get lots of other ideas
