F5 load balancer Layer 4 and Layer 7

>then it's a matter of configuring traffic balancing for applications (youtube, zoom, etc)?

Load balancing is for incoming services to a pool of servers. You seem to be asking about outgoing traffic to services like Zoom or Youtube. To manage traffic for cross-network or outgoing traffic, or to proxy and enforce external access, you can still use an F5 BIG-IP, but you will also want specialist modules (Secure Web Gateway, Policy Enforcement Manager, and SSL Orchestration).

You should reach out to F5 Sales via the F5 website to discuss your requirements and let them propose a suitable solution.
