Effective communication is a measurable indicator for career progress. There are mechanisms I can suggest to make what you say sound confident. Avoid umms, speak with good diction, be succinct when necessary. However, what it sounds like you are asking is: "How can I build influence that allows my decisions to hold merit when executing with a team?"

Conveying ideas for influence requires practice TBH. Sometimes it hovers into the sales world. You are going to get a no. That's ok. That means your pitch needs work. Your scenario I say your pitch approach might need more thought. As shared below, ideas simply need more capital. Can you share examples that work. Can you address concerns. Can you express the idea using different language. Sometimes the best way to grow here is to get feedback right away. How was my last idea received? Do you know what was missing to make it more effective?

That's all I have for now. You will do great!
