I think the big point is that developers should trust you. One of the best ways to achieve that is to participate in coding a little. My experience says the architect should avoid the critical coding and focus an quality topics. For example, style unification or linter fixes.

A corollary is that you also need the trust of other stakeholders.

For managers I'd say you need to communicate confidently and deliver. The trick with delivering is to lower expectations early.

It depends on the organization what other stakeholders there are. That is a good separate point actually: Know your stakeholders. Make a list and ask them about their expectations.
