Which Page Builder will suit this project?

I'm an experienced wordpress-based webdev. I've made my own custom themes. I've also been using Page Builders for years, starting with Divi.

My last few sites have used Bricks, which I love for it's ease-of-use, power, ecosystem and community.

But I'm totally stuck when choosing tooling for a current project!

I want to build out a very simply info-site for a client.
The client wants to present public information. Chances are, it'll be a single main page with a hero section, some bodies of text (possibly with illustrations) and a faq.

Simple, right?

But I want to allow the customer the capacity to edit the page.
This rules out Bricks.

In the past I would have reached for Beaver Builder. And I started building the site with Beaver Builder… but it feels kinda not nice, reverting to an older generation of builder that generates such a gnarly dom.

I would love love love it if I could use the block editor. And I considered using the native editor along with Greenshift.

But the admin screen for the block editor still sucks!
Even I, a deeply experience WP user and developer get a case of serious brainmangle trying to create a full-width row with three columns. I can't give my users this steaming pile of editor.

I could coach a user to work around a single glaring issue. But with both Greenshift/Greenshift and Astra/Spectra, the backend there are some pretty significant differences between the backend and frontend.

Anyway, I honestly didn't mean this post to be Yet Another Block Editor Griefpost. Apologies for that.

I want to empower my editor to edit a everso-sightly complex layout.
By that, I mean text blocks in columns, and a faq.

Their requirements for page layout might change, so I don't want to simply give them custom fields.

As far as I can tell, for ease-of-use/ease-of-learning Beaver Builder is still the best for this.

Is there an ideal page builder for this task?
Or even an adequate one?
