As someone who was in your shoes send him with your town JV team. My 2019 son played with JV team in fall 2 years ago, ended up starting on his JV team as an 8th grader, then played varsity as a freshman.
If he can make the size/speed adjustment, you will see a quantum leap in his game this season. He must also pass the dopey physical skills test come spring, but I say go for it as middle school lacrosse is practically unwatchable.
No one is watching local 8th grade fall tournaments, don't let your club guilt you. He has a better chance of being seen with the older kids.
