Free Cloudflare hosting for Pop traffic landing pages a smart idea?

Cloudflare's workers/pages feature allows a user to host a lightweight static HTML page for free that will load almost instantly on their edge network.

This seems like a perfect solution for hosting landing pages to throw paid traffic at.

Anyone have experience with this? Does it work as intended?

Any flaws to look out for or better alternatives to go with?

Any content restrictions to be aware of?

Thanks
