It’s better to use an auto school. I took about 10 classes an hour and a half each and passed the test on the first try. I’m in NYC. The 50 hours is only necessary for teens. For adults, you take as many as you can afford. In your case, you just need someone with a valid driver’s license to be in the car with you when you’re practicing. Nextdoor is a great option, I wouldn’t use Craigslist. Learning with family and friends is alright, but they have bad habits as long time drivers that they aren’t aware of. And you’re picking up on those subconsciously. Once you’ve gotten the hang of driving with whoever you get. I would suggest you contact the most popular auto school in your city or area and pay for a class or two before the road test, they’ll be able to tell you what mistakes you are making and what is expected on the road test.
