What's your go-to CMS and Backend?

I've been using MongoDB for Letter.so and it's becoming hard to manage, and it feels like it's time to move it to a CMS. I'm considering:

• Strapi
• Ghost
• Supabase
• Keystone.js

Are there any more?

I'm looking for things like versioned posts, user roles/permissions, and authentication out the box.

I've already used Strapi.io for prototypr.io, so I could get started really quickly with that. However, as good as it is for managing content, I find it a bit slow to build on and configure routes and endpoints.

On the other hand, I just cloned Ghost.org to see how that's working, and if it's possible to slot my app into it, but looks like it could be tricky.

Does anyone have any advice or experience to share that can help me decide? THanks!
