cPanel for server management setup?

New to cPanel & Managed Hosting Services

I'm just getting started with my first proper website on a managed hosting plan, and the previous discussion about cPanel best practices got me thinking. I'm a total noob when it comes to server management and cPanel itself, and I'm a bit overwhelmed by all the options available in what feels like a complex control panel. My goal is to leverage these Managed Hosting Services effectively without making rookie errors.

My main concern is avoiding costly mistakes early on.

• What are the most critical first steps in cPanel for a new site to ensure good performance?
• Are there specific cPanel settings beginners often overlook that can significantly impact resource usage or speed?
• Any common server management pitfalls a newbie should absolutely avoid when setting up a site with cPanel?

Anyone faced similar initial hurdles or have beginner-friendly advice on navigating cPanel for a new site setup?
