Want to try Linux

Hello;

I hoping to get some advice from you guys who know Linux. I want to build a workstation for home with Linux as the OS. Are there various “Flavors” of Linux or are they all the same? I understand I’ll also need to get the drivers for the network and sound cards, right?
If these questions sound basic, forgive me I’m a newbie who wants to check out Linux. Thanks for any response.
