Are there any default exceptions where wpf controls are not focusable?

In general, WPF controls work as expected with regards to being focusable or not. Things you can interact with such as button, list/items controls, textbox are all focusable. Non-interactive controls like TextBlock, Image are non-focusable. So normally, you don't have to deal with setting the value of the Focusable property. I'm not sure if this is what you're looking for but I hope this helps.
