You would need to have roof on before putting the services in and the load bearing layer is inner layer.

You can't really put much of services into the cavity as services are generally deployed during rough-in stage, when both layers of bricks are already finshed and roofing is deployed.

backyard retaining wall and raised garden bed render

Yes, waterproofing and drainage is a must. I am not very familiar with using acrylics as a base coat, generally it is applied as a top coat.

Sand cement and lime in 1:1:6 proportion (approximately) should work really well, thickness around 10 mm.
I would purchase sand cement and hydrated lime from Bunnings:

Shouldn't your frame covered from the outside before you put in insulation into the walls? And yes, you would have to put insulation in between joists too.
