Suggestions for trees

I'm looking to plant a tree at the end of my garden to give a bit of privacy and interest. Preferably something that flowers but grows up to 10 metres high with a spread of up 5 metres. Any suggestions?

All depends really on what you want  

Crab apple For wild life and colour 

Hazel   For  quick growth and nuts 

Apple  pear trees 

Flowering cherry 

The list is endless
