So, to summarize:
-Wide angle lenses have a wider DoF than tele lenses, so zone focusing is easier
-It is best to use fixed focal length lenses (prime lenses) which have DoF scales (many modern lenses don't have these anymore)
-You want to use a narrow aperture, as that increases DoF (f8, maybe up to f14, but the image will get fuzzier if you go above f9 or so, due to diffraction)
-Zone focusing and hyperfocal were made for a slightly different medium, so it is up to you to decide if hyperfocal works for the lens/camera combination that you have (along with aperture setting)
-to help with sharpness, use sturdy tripod, 2 sec timer (or remote release), lens hood, remove UV filters, and use lowest possible ISO
-adding sharpness in post processing is also important (or adjusting the jpeg settings. Press Info where you select the jpeg mode (bright, neutral, black and white,..) and you can edit a profile. You can also toggle sharpness between two types, normal and fine sharpness)

Focus stacking can also be used. And even exposure bracketing to get an extra dynamic range. It is up to you to decide how much work you want to have post processing the photo, and what software and skills you have
