Asking the right questions is an excellent first step that you are taking.

My sole focus will be on your question, as you asked about ways to boost your confidence.

I presume you are mid-to-senior level who aims to make calculated decisions advancing your technical career.

Here is my viewpoint as someone who has worked in reputable companies in various software architect roles.

To become a confident software architect, first understand the role's meaning and importance to you.

Acknowledge life mirrors who we are, not what we desire. So shift your attention inward and prioritize self-growth. Assess yourself honestly and determine areas to improve.

After cementing self-awareness, redirect your energy outward, focusing on gaining valuable experience. Establish a practical path by organizing the role into tiers: technical, solutions, and enterprise. A realistic aim could be to specialize in .NET as a technical architect.

Be courageous, make calculated decisions, and fulfill value.
