I'm sure you are aware that some people "walk on fire".
Now, from where I sit, I don't see the value or need for me to actually be able to walk on water, so that's a fear that does not constrain me.
Although... the purpose of doing so is more about transformation in oneself... learning tools about how to conquer fears...
Now, I'm not saying walk on fire... just take a moment to consider that, though... how do people "fire walk"? Well, first, it's generally not a fire, it's hot coals. Second, people prep their feet and the prep their mind, in order to walk on coals. And they also have some form of safety net, in the event that the walk goes bad.
So it's not perhaps so much to be able to walk on fire, as it is about realizing that conquering fear (or flying to the moon) is figuring out how to do it. And then doing it. Sometimes, that just means duplicating what someone else has done in order to achieve the same goal.
Like walking 1000 miles... conquering fear begins with taking a step...
And know that sometimes, when we point out our fears to ourselves, they don't seem so difficult, or even important, once we really look at them.
So start with item 1 you listed above: 1) I fear embarrassment of failure
First... really take a look at this. Yes, you wrote it and I believe you were honest and do fear embarrassment of failure. I think this is fairly common with people.
Dig a little deeper with this one. Embarrassment of failure is something more than just failing. It's being embarrassed about it. IOW, it's often more about shame.
What about shame are you afraid of? Where does shame come from? In your words and thoughts?
