Using Forge 1.19.2 Is there any mods that would allow me to control entity clearing and restart time

[summer bay]

I want to have something that can clear entity's to help with potential lag as well as world spawn and protection, just admin stuff like essentials. Maybe also a message to countdown restart

For the entities just /kill @a

There's also this amazing thing called google to help the rest of your problems.

I can’t remember the names but Google those things with “forge” at the end im sure everything you need will come up
