[Star Wars] The thermal exhaust port of the first Death Star faces out into space, so why did the X-Wings approach it down the (laser lined) trench perpendicular to the port?

To hit such a small target under the heavy jamming that usually are faced in combat, you  need a steady approach, without much dodging or fidgeting around.  
This makes you an easy target for bigger guns, like Turbolasers.  
It is worth mentioning that the Death Star had a lot of those. around 15.000 bigger guns of varying types and models.

The trench, however, was below almost all of them, making for a much safer approach.
