CMS with sections support?

Question

CMS

Good day, experts. Please tell me a CMS that supports working with sections.
That is: he created 5 different sections (blocks) and the client subsequently inserted them in the sequence he needed on the pages, it is also necessary that he (the client) does not pick in the code, but corrects the data of these sections in a certain form.
It does not matter how I will create these sections (in files or through the admin panel), the main thing is simplicity for the client.
This is used in the Advanced Custom Fields (ACF) plugin and frameworks in Wordpress, just do not want to use heavyweight WordPress in low-budget and simple projects.
I have already reviewed a bunch of different "light" CMS and did not find one that suits this task.
Please do not offer to write yourself.
