So here's a related question...when would you use "as" in this context?
You mean in the ‘thank you for XYZ’ context?
I’d say pretty much all the time, as longa as you’re not talking about Ulsterers. Using
ar son here is mostly limited to Ulster.

Ulster for the initial mutation, but are you sure Ulster people would use "as" after "go rabh maith agad"? I'm not sure.
Ar son is more common, but I’m fairly certain I’ve also heard
as occasionally. Could be a regional thing (I suppose they’d be more likely to use less Ulsterish forms in South Donegal than in North Donegal, for instance), but I’m not sure.
I think in brief statements, I’ve heard more people say
go raibh maith agat as sin than
go raibh maith agat ar a shon sin—in fact I’m not certain if I’ve ever heard the latter.
