Similar size company and over the past 2y we transitioned from technology based teams to stream-aligned teams that include engineering, product, and design within each team. The book Team Topologies is a good reference for this and fairly quick read.

In my experience, the pros of stream-aligned teams vastly outweigh the cons. The major pros are reduced cross-team dependencies and fewer hand-offs, more ownership over work, focusing people on a narrower set of customer/business problems, and that stream-aligned teams are easier to refactor and decompose as the organization grows.

What I learned along the way is that you will still have some cross-team dependencies based on technical expertise. So you will benefit from your engineering leaders explicitly and regularly discussing these needs, then incorporating some resource sharing into their plans. For instance, you might have an engineer who really knows one area of the product or technology brought into another team's kickoffs and design reviews or even joining the other team temporarily.
