I use Aperture Priority most of the time, and leave the camera in that mode, aperture wide open, and Auto ISO when I turn it off. I can just pick up the camera and taken a pic.
When I get a new camera I try to get accustomed to how to change common settings, Exposure Compensation, Focusing on/off etc, mainly by playing with it whilst watching TV. There is normally a period of adjustment, especially if it is a new brand of camera from what one may have had before.
A lot of cameras have a 'my menu' option, where a lot of different settings can be grouped together for quick and easy access, such as changing focus modes, turning face detection on/off, turning Auto ISO on/off, Formatting the memory card etc. It pays to take the time to populate this menu option, if your camera has it, with the settings you may use occasionally, rather than spending ahes going through the many pages of the main menu.
Some cameras have programmable memory slots where the mode, focusing, fps etc, amongst other things, can be stored, and that is any easy way to change a whole load of settings in an instant. On one of my cameras that has that option, I have stored setting for generally walking around, and another set up for sport/action, which turns on high fps, and changes the focusing mode, as well as some other settings, which can be useful. On some of the newer cameras, this can be set up on a function button on the body, to flip between these things even quicker.
These things can only be found by reading the manual, and only become second nature through use. There are no shortcuts.
