This is how you get photos that are sharp throughout the frame: Use a lens that's sharp throughout the frame. Stop that lens down to where it performs best. This is usually around 2 stops down from wide open. You can look this up for most lenses. If you are relatively close to what you're photographing or if there is great distance between important subjects you will need to resort to combining several photos, each with a different focus point - a.k.a. focus stacking.That is how really, really sharp photos of cityscapes are made. To get even bigger resolution and sharpness you can also combine several photos vertically and horizontally. Also, using a medium format camera or a DSLR with 40+ megapixels can help if your lens is up for the task.---A cheaper DSLR with the kit lens is not going to give you perfect landscape/cityscape shots.
You forgot the most important: use a tripod, and switch the image stabilization off!(and use a remote control maybe)

Hard to do focus stacking without a tripod.A remote control is good but often not necessary since you can just use the shutter delay function on most cameras.
understanding how to use hyperfocal distance

I wouldn't normally want to have distant objects in focus if I've got a subject of interest very close to the lens. Of course, another alternative is to use tilt on a t/s lens. That was a common approach with large format on film in the old days. Wide-angle T-S lenses tend to be a bit expensive, though.

Anyway, the biggest use for it is with cityscapes where you are RELATIVELY close (not 10 feet) but you want the image to be tack sharp from the first skyscraper to the last.There is always just ONE spot with perfect sharpness, so it's just all about how much deviation you are willing to accept, or what's visible. To me, skyscraper details such as windows should all be tack sharp for a stellar image.
Well take this one:https://www.shutterstock.com/image-photo/doha-qatar-february-17-2016-highrise-615071813I got the palms and the buildings at a focal length of 34mm on f7.1 on a Canon 6D (17-40L f4 lens), with no problems, handheld at 1/200s.Perhaps the OP shutter speed was too short for handheld or he was shooting at f22 or above and getting diffraction.

The OP didn't answer what camera he was using. The only time I got rejections was when I had a defective camera and didn't know it until the rejections started coming in. That camera went back and I got a new one and never had a problem again.
