(I had been a Scout for a few year and got a lot of benefits from it, but I know that my brother bullied a lot the younger scouts, so this is a real problem)
But for sure, do what you think is best for your kids.
I don’t have kids yet, but I think that scouting is a good option. Still, the experience one child will have will vary wildly from one scout association to the other and one local organization to the other, mostly because it depends a lot on the people he will end up with.
Also congrats on your engagement ! I always had a lot of respect for those who helped run our groups.
I was a cub in the early '90s in a deprived ex-mining town in the UK. Fighting and bullying were rife.
My parents were warned by other parents they knew not to send me to the scout troop, as it operated more like a gang than a troop.
