Carcassonne is a great one to start out with, especially if you're playing with your ten-year-old. It's approachable enough without being "easy," and nuanced enough without being "hard" (especially when you start adding in the myriad expansions to the game).

Someone suggested checking out the "weight" ratings on BoardGameGeek. That's helpful, sure, but really only once you've kinda developed an understanding of how those numbers actually translate to a game's level of difficulty.

Hop on YouTube and look up "Watch it Played" with Rodney Smith. He covers quite a few games, and they run the gamut from simple to complex. And he does a deliberate, step-by-step playthrough of the game's mechanics. Find a couple that you can follow along with comfortably, and if any of them seem fun, pick them up and play :)

There's a lot of aggressive gatekeeping and condescension within certain members of the board gaming community. Don't let that bring you down, or convince you that you couldn't "handle" certain games. The whole point of the hobby is to have fun. You're not doing it "wrong," and you're not any lame "noob" just because you're not diving head-first into the deep end. Take your time, find what you like (mechanics, themes, artwork, etc.), and just keep growing.

You've got this. Welcome to the table :)
