With my fesuce, it's mostly open and as I'm cutting at 3.5-4" during the warmer season (here in georgia) I usually can cut pretty easy. I start out at a "corner" of the property, find a point at the opposite end of the property and keep my eyes fixed on it and drive towards it. That usually sets the precedent for the rest of the passes. Then I'll usually line up the inside of the front tire with the cut line of the previous pass so I get good coverage. I'll usually go back and forth to get that "striping" effect.
I usually will cut the edge first going clockwise around the turf (blowing the clippings into the yard and not into the beads) twice and then start to the main mowing.
Now I'll get a little creative sometime and try different patters, (circles, squares, triangles, zig zags, spirals) just for giggles if I have the time. It takes longer but it gives me something different to look at.
For my front yard which is pretty small, slightly sloped, and irregular builder grade bermuda it's a little harder to mow with a bigger deck and at a short height. For me it the trick was doing it wrong (accidental scalping at the wrong height, blade gouges when turning, tires tearing up the grass when spinning, letting the mower idle over the grass for a period of time), once or twice and learning what not to do on that turf. Once I learned to raise the deck a little when turning around (foot deck lever FTW!) or when going from a flat to an angled surface, the cut quality went up. Also I slowed down when turning. It's not perfect and doesn't look as good as when I used a 18" push mower but It looks good enough.
In a perfect world, I'd still be push mowing the bermuda with a 18" deck and using a huge 72" deck for the fescue. I just don't have the time/space/money for that.
