Haha. What happens to you is normal. With Webflow or not, the Primary menu is a sensible and difficult part of a design. One of the most important too. So many questions to begin with… Should it be visible, should it hide behind a hamburger icon on mobile, should it make a semantical sense, like a phrase, should it be organized with a visual hierarchy? And so on…
Designing it for your target (here elderly) is the thing to do.
Webflow comes with a default structure that acomodates for the most often seen number of links. It’s easily adaptable to your needs.
If you find exactly what you need and show it to me in a way or another (mockup image, draft…) I’ll be happy to help you build the appropriate structure for it
