Mohist
Minecraft Forge Hybrid server implementing the Spigot/Bukkit API, formerly known as Thermos/Cauldron/MCPC+

WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
I know that CoreProtect is a Spigot plugin, and that forge is a different beast entirely. But I've looked into Mohist (https://github.com/MohistMC/Mohist) and it looks like it has what I need, though not really any support for 1.19 quite yet.
