Which approach works better?

I’ve been working on a Product Detail Page (PDP) for an e-commerce platform. The product is highly customizable, but the flow still needs to feel linear and guided, with a few additional features built in.

The main focus is on UX over pure UI specifically how well we can funnel users through the flow and make the experience as smooth as possible.

Note: The higher information density is intentional. The target audience is enterprise/organizational buyers who need detailed specifications, not typical individual consumers.

Open to all kinds of feedback.
