Since the total height is 18', I was planning on using 2 sheets of 9' shear and providing blocking for both at the 9' height. So with the 2' wall that would be approximately in the center and the shear would overlap upper and lower plates by 12" which I think is code. Does that sound about right? Thanks

No, the sub floor sits on the wall at 10'?" to match the upper floor and the next wall sits on that. You still need a fire stop at the ceiling height below. So I see no advantage to 9 ft sheets.

So you would have 2- 2x6 top plates and a 2x6 block directly under them? Most of the framing around here aren't using mid-stud fire blocks,open from green to top plate.-----This adds another question. Does the drywall on the 1st floor ceilings have to be fire rated? Thanks

Fire stopping so fire does not travel from wall to floor system or the other way. That is beside the mid wall one that we never get called for but some places watch that carefully.
Yes ceiling drywall applies to all ceilings,

On the exterior then you would use 8' shear top and bottom and a 2' band in the middle.

I don't see why you shouldn't use 2 - 9' sheets on the outside with blocking, if your total height is 18'. Makes perfect sense.

You could save the work of blocking and put the break at the wall plates. There's no code here that says shear needs to go 12" past your plates. As long as you follow your nailing schedule it shouldn't matter.
