What is a lightweight modern CMS with basic functionality?

Question

CMS

The bottom line is that you need a CMS that will have the functions of creating pages, placing text content on them through a WYSIWYG editor, a news-articles module, a user-rights system and the ability to install your own modules.
It would be nice if there was a photo albums module with a bulk import function and a simple tree-like catalog.
why - as a rule, I make sites not complicated and for the client. those. only the functionality that he needs (if the catalog - then there is a name, price, description, select a photo and that's it, etc.). for a long time on one CMS (subdreamer) he did all this, he did his modules, but the design of the admin panel and many things is outdated, and there is no desire to cut his bikes, I would like the basic described functionality to be already ... subdreamer has a slightly strange licensing and update policy, I want to try to find something else.
I don’t consider any drupal, wordpress, joomla because of their slowness, monstrosity, and so on. I like when there are exactly those functions that are needed and nothing more.
ideally on boorstrap think something like it. there are heaps of admin panel templates on it, but I will be collecting my bike for a long time ...
