I'm a vlogger, so frame rate doesn't matter too much to me. I just stand there and talk to a camera haha.
I use 24fps though. 24fps is commonly used to give a cinematic look. Also the file sizes are smaller since there are less frames per second.
Personally, I would just try out the different frame rates and use what you like.
Edit: I forgot to answer your question, but youtube accepts most FPS
"Common frame rates include: 24, 25, 30, 48, 50, 60 frames per second (other frame rates are also acceptable)."
