I usually run stranded as it is much easier to work with, and when exposed, easier to install without kinks.

GEC can be solid or stranded, insulated, bare or covered. 250-62

310-3 exception would apply. Therefore, the GEC can be solid when installed in conduit. I'd like to than Don for pointing this out to me previously.
