Putting something smaller (pergolas etc as suggested) round your seating/dining areas is a simpler, but usually more effective solution.That would be a far better idea than trying to put trees along a boundary - they'll take ages to be effective, unless you can afford the price of mature specimens and have the knowledge to get them established.
The shrubs - as explained - will take a while to screen that fence too, although you can always put a few shrubs in place anyway to get rid of the bare look and having something attractive to look at. There are loads which are easy to work with and readily available. We can offer plenty of suggestions for those if you like
