Can we talk about architecture of such system or is it ‘just design’? If so, then SOA or EDA does not apply to it and being CQRS may be a one of the most important fact about this system’s design, right?

Regarding these ‘systems of systems’ I agree that patterns are about internal structure (boxes) while styles are about communication (lines).

W can consider different “levels” of Architecture (all are important):
1. Application Architecture – now to structure code (responsibility) in one “module” of whole system.
Application architectures ex:
- layers (not tiers, different layers)
- microcernel
- ports&adapters (imho it’s unification of Layers + P&A + Pipes&Filters)
- CqRS – hmmm can be used as separate Application Arch (or as inner structure of P&A “hexagon”)
- … ?
2. System Architecture – how to structure (encapsulate and integrate) “modules” in bigger “universe”
You mentioned:
- SOA
- EDA (Pipes&Filters?)
- …?
3. Deployment, Security, Scalability,… Architectures

According to this semantics ES is imho “just” a persistence technique.

This is just my private “mental scaffolding” that helps to grasp and categorize ideas.
What do You think about this approach to looking at different “zoom levels”?
