WordPress builder plugin?

Question

WordPress

Good afternoon dear friends. Please help me choose a simple constructor (or a combine, I want to see both options) for editing text inside ready-made one-page blocks.
I'll try to explain what I mean. In general, there is a landing page, the client expressed a desire to edit the content from the wp admin panel (usually I just do it through a custom page and without bothering to make changes manually, through the code). But alas, they demand it)))
Of course, it would be possible to create a number of entries and simply pull up the text from them or write your own bike, but it seems to me that there is a lot of unnecessary trouble. And besides, I'm sure something similar already exists (before, by the way, there were either cform's or something like that).
I hope you understand what I meant. Thank you in advance for your help and your time =)
