As you have understood, you have to fight with two contrasting needs: you may want to use wide apertures to avoid diffraction and to get fast shutter speed and clean background, but you also need to use small apertures to get a good depth of field. There are various "workarounds" to get the desidered results. Whenever possible, try yo photograph the subject from a low angle, to frame it against a distant background: a close background tends to be distracting, while a distant background is more uniform and it does not steal the attention from the subject. Other than that, using a long lens helps to get a clean background even at f/11 or f/16: the same photo has a more uniform background if it is taken with a 180mm instead of a 50mm. Remember that the depth of field is the same for every lens - at f/16, you have the same DOF both with a 50mm or a 360mm (the combo that I use, 180+2x) - but the 360mm has a narrower angle of view, so it frames a smaller portion of background against the subject, and you get a more uniform BG.
