Writing fiction is just a series of decisions. It is deciding what word to use, what name a character has, where the story takes place, what happens next, who says what, why someone does something. Making decisions is progress, and progress is the way to get better at writing.
Who cares if the chosen word isn't right? It can most certainly be changed, or it may be fine.
Who cares if the name Frederick von Gorman III is a silly name? It's good enough. What's important is that the character has a name, which is one less decision to make. Now you can decide what that character does, where they are from, who their siblings are, and everything else about them.
Don't get hung up. Keep making decisions. Keep making progress. Keep writing.
