In cases where the client doesn't require frequent changes, svelte/gatsby does the job lightly.
Webflow was used for ecommerce with hundreds of products/product variants. Dynamic & easy to update for the client.
It would be nice to eventually be able to build web apps with SSGs/SSRs while also having a no code editor for the clients. An all in one native toolkit (like a headless cms embed). But clean & reusable code is of highest importance.
