Where in the uk are you Aimee, and what age are you planning on getting the goslings? The earlier the better for them to imprint on you - i got my two boys at 5 days old and they follow me everywhere.
@Goosebaby is correct, worth checking with your neighbours about the noise, luckily most of my neighbours have been fine about it, including directly next door but you always have that one busybody who has a problem - they will be noisier than your son for sure and you can really only research which breeds tend to be the most docile when picking
As others have said, they're messy and poo everywhere all of the time, you cannot toilet train a goose and the nappies only go so far (i think its a bit unfair to have them nappied up for long periods) so be prepared to have towels down all the time and to clean up every day.
One more thing, the UK has an avian flu outbreak at the moment and just like us humans with covid, birds have been put into their own lockdown and cant go outside unless under some netting seperating them from wild birds - it might have eased by the time you can get some, but i would expect goslings to be even more vulnerable to it
