WordPress

Hi, I'm an experienced webdev but new to wordpress and was asked to build a maintainable webpage for a hobbyist group.
In the future they want to be able to maintain as much as possible themselves and for the remainder search for as broad a range of web-devs as possible.
Due to that I found it reasonable that they specifically requested I use wordpress, but they also requested elementor and astra.

Taking basically one long look at these I threw both of them out immediately and have been using a basic theme (twentytwentyfour) and no plugins so far.
My contact however keeps insisting "all the tutorials use astra/elementor" or variations thereof, so just to cover my bases here,
What is the community consensus on astra/elementor?
What plugins themes would you recommend for such a situation?

The page has a bunch of static text-pages, a somewhat complex page-frame (with top and sidemenus) and a few "article pages" (Where later maintainers can easily create "posts" i.e. subpages).
Running costs are unacceptable and I would very much like to avoid one-time costs.
