There are a few things to consider here, mainly functionality and design.
You can easily create custom designs with WP Divi for instance and that would give you the design you are looking for and the power of wordpress.
The big question here is: Are you willing to learn a new way of doing things and/or alternatives? I cannot recommend Pinegrow because I haven’t explore it beyond the basics. It will all depend on what you are looking for.
With Webflow you have the design flexibility plus the animations / interactions that can really improve the UX and a CMS that is super easy for content updates. That comes with a cost (CMS sites have to be hosted with Webflow) and some limitations regarding Wordpress functionality, but with Webflow you don’t have to worry about backups, security and updates, that is all included on your hosting package.
Some integrations might not be automatic and there is a learning curve to it, but if you are not looking for a big project with ecommerce, user logins/user management, booking systems or dealing with a lot of references (categories for instance) I’d definitely recommend Webflow.
