Modern C++ can improve safety and clarity in embedded systems, but only if the team understands what the generated code is doing and where the boundaries are.

• Use stronger types where they remove ambiguity
• Prefer compile-time checks where they simplify runtime code
• Avoid abstractions that hide timing, allocation, or ownership
• Measure binary size, startup cost, and debugability instead of assuming

If you are evaluating templates, constexpr, spans, views, or containers for an embedded target, post the constraints. The right answer depends heavily on RAM, tooling, and how the code is debugged in production.
