For a full size pistol, striker fired. For a CCW gun, DA/SA.

I don't consider the fancy lever on the trigger to be a safety mechanism except for the rare circumstance if you drop the gun or something. And I prefer not to have a safety lever, so a long DA first trigger pull is my safety in a concealed weapon.

For a "going to war" gun (general range fun, IDPA, or zombie apocalypse), I'm fine with my M&P 9 and/or Glock 21. I like the rapid trigger action for a purpose like that.
