I wouldn't consider myself an expert in any way, but it takes less than an hour to get up to speed with the Latex necessary to compose a nice CV/resume. Most people spend far more time wrangling with a word processor to get a much uglier result.
I learned basic Latex, just the minimum necessary to get started. And now I just Google what I want and use the code verbatim, never bothering to understand the internals. I thought I was the only one who did this until I saw that most other people in my university did the same.
Honestly, that's what makes LaTeX great. Formatting is decoupled from content. If you want to make a formatting change, you can Google it and chances are that somebody else has done the same thing.
In Latex usually get nice results with the result settings, but if you don't you can spend hours getting it to look the way you want.
