The North Dome Regular Route used to be, still is in some places, called 5.7. For long and sustained, and with all kinds of new and strange moves and some routefinding, I certainly wouldn't recommend it for a new 5.7 leader, even one who could manage some of the one pitch delights mentioned above.
I've done most of the pitches mentioned and I'd have to say the beginning of Doggie Diversions on Camp 4 Wall is the hardest 5.7 I've been on in the Valley but I guess it depends on how comfortable they are in a squeeze chimney.
Actually I got your answer by far. The South Face of North Dome route in entirety is probably the best sandbag 5.7 full adventure day to be had in Yosemite. Great route, no cake walk, all types of climbing, and a few fun but not bad runouts on a few sections for the grade.
