I'd go garage keep the storage space inside!

Airing cupboard all day long unless you really need the space.
One of the biggest complaints people have is how long it takes to get hot water out of the tap. This is due to combis not losing heat into the pipework like a hot water cylinders. So the further the pipework has to run the more water you have to run off before you get hot through.
Usually the airing cupboard is central in the house and not too far from all the taps. The only thing I would do extra would be to take out the old 22mm hot pipework (if you have any) and make it 15mm.

Depends how cold your garage gets, the inlaws have theirs in the garage but in the winter it has to keep kicking in over night to stop from freezing up which does bump the gas bill up a bit.

Friend of mine put is on the loft, never had any problems, in all honest if i was doing my house all again this is where mine would go

Mines in the airing cupboard, the boiler gives off a bit of heat too so the airing cupboard is warm if you wanted to put towels in there. Also means its easy to access for servicing / re-pressurising etc.
Word of advice; you need to be able to inspect the entire length of the flue from combi to exhaust to the outside world, if you cant then British Gas and co wont take it on and your probably in violation of CORGI or something (im not a gas man). We had a combi in an airing cupboard, with the flue going into the void in the wall and then up through the roof - caused me no end of problems.

What is the advantage of decreasing the pipe size? (other than increased friction/reduced flow..)

Presumably to reduce the amount of cold water that's stood in the pipe and needs to be pulled off.
You'd have to have a really long run to make it worthwhile.

I had an old system replaced in the airing cupboard. Honestly if you don't need the space in the garage then get it relocated to the garage.
An overlooked benefit is you remove a leak risk from upstairs inside the house to the garage! Great when the boiler does eventually go wrong.
Also you future proof your options as theres going to be more space in the garage if you want to go back to a tank option surely?

Ours is in the garage, best place for it, don't want to hear that thing all the time. Its on the wall that is the house, so the pipes go straight into the house. Freezing is a non issue, its the best place for it, if it wasnt in the garage i would then need a frost stat for the pipework and the boiler would fire up exactly the same as it does now.

Correct and not necessarily
A lot of modern taps/showers and fittings nowadays are designed to be more economical/efficient with water. Which means they draw it off slower by using less, which means having to wait longer just to empty a 22mm pipe and nearly all cylinder systems have the hot piped in 22mm. If you can fit the boiler in the garage and keep the pipe runs short to the taps then great. But usually the airing cupboard is more favourable. If noise is a concern then get something like a Vaillant, they have a quiet mark accreditation.
Several boilers on the market also have preheat abilities, which shortens the wait for dhw even more. Vaillant, Worcester, Ideal etc.
There is also less likelihood of the condensate freezing when it's kept in the house. We went out to plenty of frozen condensate pipes located in people's garages earlier this year.

Disadvantage of that surely is that you'll overall be reducing the flow rate (due to increased friction)
I know what you mean though, my shower takes a while to get hot, but the pressure/flow is good!
