What colour rose might you have over your arch? Perhaps a nice scented one. I've gone for a white scented combination with a Madam Alfred Carrier rose and a Duchess of Edinborough clematis growing up through it.
There are some nice tall grasses that I've seen as screens. They make for a lovely texture, with some movement and change of colour. Plus a gentle rustling sound. Sorry I don't know the names but I'm sure other clever folk on here will, or ask at your local garden centre. Good luck with it!
