Hey Guys! A little Unrelated...but could use some advice

I am moving from New York and I want to sell some things before I leave, there isn’t a lot of stuff that is big item and I’m curious what the best outlet would be to sell things on? I’ve never had to do it before, does anyone recommend any apps or any services I could use besides you know, Craigslist. I always get fake people wanting to buy stuff on Craigslist and I hate it.
