You can configure:

A filter of types, spawn reasons and probabilities
Entities' max health, effects, and equipment
Templates of effects and enchantments
Random distributions for the majority of numeric values
Entities' following range
Schedule for enchantments and drops

You can solve the following problems:

Increase the velocity of specific entities, thus make some enemies more dangerous naturally
Equip entities to protect them from environmental influence
Make items droppable to award a killer
Make "Fridays with neither thorns nor good item drops"

Commands

customcreatures reload - reload config from disk

customcreatures apply <handler> - apply a handler to currently living entities

Permissions

Access to 'reload' command: customcreatures.reload (default: op)
Access to 'apply' command: customcreatures.apply (default: op)

Configuration

Default configuration file

I assume the typical server admin config lifecycle for this plugin involves having their own custom configuration, which you keep in a dedicated part of the config file and migrate from version to version.

The first section of 500 commented lines shows the config structure you can use for your handlers. Each potential handler config option is used in the real config below, so you may check it for examples.

For example, you see "jump-strength" in the structure, where its type and mechanics are described:

#     jump-strength: float-value:0.0..2.0 ### https://minecraft.fandom.com/wiki/Horse#Jump_strength
#                                           ### Horse's jump strength ranges from 0.4–1.0, with an average of 0.7.
(...)

Then you search its real usage

cool-horse:
(...)
  entity-specific-attributes:
(...)
      jump-strength: 2.0
