My parents had a south facing garden which meant curtains were regularly closed to stop blinding us (on a hill so the houses behind were lower down.)
My current house is SE facing at the front and NW facing at the back. We do not have houses next to us, we are massively offset so our back garden gets full sun to every part of the garden, plus we have a small side garden which is to the west.
The benefit is you can find sun if you want it or avoid it if you don't. Ds2 was white blonde as a toddler so having his toys set up on the patio in the shade was a blessing when we first moved in.
Re darkness our lounge on the back has french door bay window plus another window, the other room at the back is the kitchen so it is cool when you are cooking which I love.
As a family we are not sunbathers, we don't lie on a beach for 2 weeks because it is just too hot, hence why we love this house, you can sit in sun or shade. We love it.
I think people always imagine houses in rows so a north facing garden will be shadowed, mine is not next to any other houses despite living on an estate. When we go to sell I shall be making sure the garden is in full sun when the photos are taken so it can be seen.
