If you're trying to figure out what CMS to go with, these are some tests you can do before you go hard building your site.
Can you easily change your page title? Can you easily change your meta description? Can you easily change your URL slugs?
Can you do it for individual pages too? It should be very easy to do that.
Then you try to crawl your site with Screaming Frog. Allows you to crawl websites, see the pages on websites, see the page title, the meta description, the URL. But if right from the jump there are issues crawling your pages, maybe they're just not being crawled.
Try other CMS's. I like WordPress as a CMS, Yoast as the SEO plugin, Elementor Pro as a page builder. These three together, they're great for making pages that rank.
