Are Amazon creators on YouTube and Instagram really worth my time?

I am just starting out on Amazon FBA and I am quite confused about which creators to follow. I have been hearing good things about My Amazon Guy and how he helps with everything Amazon -related. At the same time, other sellers have recommended Jon Derkits, Brandon M. Young Owais Amin, Christopher Grant, and Vanessa Hung | Amazon Expert for marketing and Advertising & Promotion.

I have checked some of them on YouTube and instagram and everyone seems to help in one way or the other. I would like to know the Amazon FBA creators you swear by. I would like to follow creators who:

• Share troubleshooting content regarding even minor issues with Amazon selling

• Work in the Amazon Private Label or Wholesale category. I wouldn’t mind creators from retail arbitrage/ online arbitrage (RA/OA) or Dropshipping if they offer valuable general Amazon content as well

• Are experts in their field

Also, creators with niche expertise in private label would be a plus.
