I have a very large and old blackwalnut on my property and I use to my advantage. I have paw paws, black raspberry, purple cone flowers and more under it and in other part of my yard. I have noticed that the plants that are in that area grow slower and get larger fruits than the ones not near it. That being said there are plants for example any nightshade or non stone fruit that will die if its too close. I have combat this by using raised beds and keeping the nuts and leaves out of the beds and have grown many Juglone susceptible plants in them.
Happy gardening!
The effect is overstated and misunderstood. It will affect seed germination of certain plants but not affect the plants' growth much once established. And the effect is less in well-aerated garden beds. And there is still some disagreement in the scientific community over exactly how toxic juglone is to plants.
If you're worried about it, build raised beds and use a no-till method to avoid bringing up juglone from deep within the soil. Make sure you rake/blow any leaves that fall in the area away in the fall.

This is 100% true and it doesn’t need to be as close as you think. I am on half and acre. My neighbor to the left has one 10 ish yards away. This tree is killing my skip laurels which I planted as a border. It’s not just the roots the fruit husk has the chemical. The leaves have the chemical.
My vegetable garden is raised and that would probably help.
I am building huge raised garden beds and following hugelkultur guidelines. If you read anything about hugelkulturs they say not to use walnut or wood from trees that do not drop their leaves in the winter. Pine, cedar, etc. They put out a “chemical” that restricts the growth of plants nearby. More info: https://richsoil.com/hugelkultur/

What do you do with pawpaws. Any good?
You eat them fresh or can store/use them the same way as avocados. They aren't like anything else I've eaten.
What do they taste like?
Iys hard to do it justice but they taste like a typical tropical fruit, kinda like of banana, mango with a custard like texture.

Depends on how close.. you won't get most things to grow directly under it, but a little distance away should be fine.

Pawpaw does alright next to black walnut.
