Just want to know if WebFlow can handle big blogs with a lot of articles? We wanted to migrate our website with 300+ blogposts to Webflow. Does anyone know if there any limits for content? And can webflow engine and cms handle a lot of pages also providing good optimization (90+ for google speed test)?
Webflow supports up to 100 pages. The CMS provides support for 2k-10k items where a blog post would be one.

As for functionality that is clearly provided in the Webflow University.
There are limits and many of them are listed in this post. ► [LIST] Feature Availability & Limits
I can’t attest to that as current since I am not the maintainer.
If I was coming from WP I would spend some time understanding the rich text editor and its limitations against the WP block editor. They are not equivalent. The other thing you can’t do is have unique templates for posts. WF only supports one template per collection. People try to overcome that by using conditionals but the conditional content is just hidden and still present in the load. Another area that is currently weak is responsive images inside collection item rich text fields as that is not currently supported as it is on pages.
I have lots of WP experience and personally prefer it over WF for blogging. You might feel different when you are done evaluating it.
