Feeling a little lost..new build garden ideas please!

Hi we moved into a new build about 18months ago, I levelled the back garden and planted grass seed.  The size is approximately 11m x 11m. And the soil is clay soil.
The garden is east facing (we also have a street light, the rear of the house backs on to a cul-de-sac). With the right hand side in shade later in the afternoon.
We want a child friendly back garden, growing fruit and vegetables.

I am a complete beginner and would value any advice please.
1. I'm ideally looking at planting along the left and back fence fruit thornless fruit bushes. Any suggestions?
2. I'm also thinking of two raised borders for potatoes, kale, courgettes, radishes, salad leaves/spinach. Any advice on what else might grow well? And perhaps a small raised border for strawberries?
3. Lastly I'm thinking of adding some containers for runner beans, garlic, herbs.

I'm not sure if I'm being overly ambitious for someone without any knowledge, so any guidance would be very much appreciated.
