You should be able to share content with stakeholders as guests. They can create free accounts and use them to access whatever you want them to see. We do this with other teams within our organisation - currently, our team is the only one with a Premium subscription.
If you want to control it even further, you could set up a separate workspace and invite stakeholders to that. We do that with some of our external contractors. They have access to what we’ve shared with them, and we can allocate and track their workload really easily. You could do the same thing with read-only projects.
I hope that’s helpful!
