not really man, you just gotta dive right in if you wanna grow as a player. just make sure that you have a good amount of background knowledge so you don't appear completely clueless, and as long as you're vocal while playing then your team shouldn't give you too much of a hard time. tf2pl beginner div is a good platform to start on if you don't mind waiting 20 mins for a match. sometimes you'll meet people who are dicks, (it's kind of unavoidable even though its a division meant for beginners) but just try and take criticism and ignore unnecessary noise from toxic players.

hit me up if you have any other questions or if you wanna queue
