Shower Waterproofing

I am planning a shower with the following components:

RSS Custom Base and Curb

GoBoard for shower walls

Schluter All-Set

RSS Band and Corners

FloFx Drain

A couple of questions:

1. Should I use RSS sealant or GoBoard Sealant for corners, seams, screw covering

2. Do you see any issues with this overall approach

As always, thank you for your help and insight.
