That's correct. If you were building a new home, you would be required to have locks that can be unlocked from the inside with no key. As far as the knob or thumb, IIRC the only time that comes into play is when building multiple units, such as an apartment, where one unit in the complex has to be handicap accessible. For your own personal home, it doesn't matter which one you choose, but a good rule of thumb is not to use a double sided keyed deadbolt, even if you leave the key in it. I would suck to burn up in a fire because you broke the key in a panic trying to get out.
