US taxes: filing FTC to receive child tax credits. Any accountant recommendations?

Hi everyone, Here is a quick summary of my situation:

-U.S. citizen living in Japan

-Have a young child that has an SSN

-Found out about child tax credits

-Learned that I need to file under Foreign Tax Credit (FTC) instead of the usual Foreign Earned Income Exclusion (FEIE) in order to receive the child tax credits

Now, the last point above makes sense, but when I looked up more information about it, I basically see a lot of posts/people saying that filing FTC vs. FEIE depends on your personal/financial situation as to which one would be more beneficial financially… and I have no idea. I'm wondering what others in my situation have done – did you need to consult with a tax accountant to find out which way to file would be better for your situation? If so, do you have any recommendations for who I could go to to figure this out?

Basically, the child tax credits sound great, but I read that once you file under FTC you can't file under FEIE again for 5 years and basically I want to make sure I wouldn't be making a mistake by doing this. My tax situation is not complicated at all (no real estate, income outside Japan, etc.) if that makes any difference.

Thank you for any advice or accountant recommendations you can give!
