Building a transparent bridge filter with OPNsense sounds like a solid project. I've worked with it before, and it's pretty straightforward once you get the hang of it. You'll be setting up OPNsense in bridge mode between your network interfaces. This will let you filter traffic without altering the routing. You can use the firewall rules to specify what to block or allow between the interfaces.
One thing I've found super helpful is running an ip stress test to make sure the bridge handles traffic well. It's a good way to gauge the performance and ensure everything's running smoothly without hiccups. I would suggest starting with a small test setup to play around with before going full-scale.
