Yes, it absolutely can, it’s super easy! Just swap your Minecraft .jar with Paper and it’ll do the rest. It’s a tiny bit harder to go back, but only marginally.
Out of the box, aside from huge performance benefits, Paper is virtually indistinguishable from vanilla, but it also opens the door to a whole world of easy-to-use server-side plugins.
Edit: (you should still make a backup before swapping, just in case)
Lots of people think naturally grazing cattle is somehow less resource intensive than the alternative.
It’s the “yeah, factory farms are bad, but I get all my beef from my made up neighbor who runs a sustainable farm” crowd.
