What sort of sand should I get?
Why would it matter? The one advantage of dried is that you can sweep it into the joints faster.
I might be tempted to use dry sand/cement to lessen weed growth.

go to Wickes, They sell the right stuff.
I'd be inclined to use sharp sand bordering on fine gravel if the gaps are as wide as you say. It is less inclined to wash away, drains quicker and so harder for weed seeds to germinate in.
You can dry sand in the sun on newspaper if you need it free running. (but it is cold, foggy and damp up here)
Well, given a half inch gap, it doesn't need to be kiln dried. I agree a bag of sharp sand should be fine.
If your trying to fill the 0.5mm gap between block paving blocks, it's not that you can sweep it into the joints faster - it simply won't go into the joints unless it is kiln dried.
However, for a big gap like this, it doesn't matter.
Not convinced that'll work well.
Sure it does, it just doesnt free flow in. So you chuck the sand out and let normal traffic plod it in. Dried sand is instant, but it costs a bit more. Doesnt matter to most of us, but not everyone.

Just use ordinary sand. Sweep in and then hose down. You will need lots more than you might think.
B&Q do a "special" mortar for paving gaps. It's fine, dry, and fast setting. Easy to use but I wouldn't go out and buy it specially
25kg bags. BUT in my case some bags were damp so it was not dry as advertised. £4.15/Bag
Just bought half a dozen bags of kiln-dried sand from them, had to drag as many damp bags off the pallet onto the floor to reach the dry ones, pointed this out to the staff who simply shrugged.
Any comparison between slabs and block paving is meaingless as the purpose of the joints are completely different hence as are the materials.

sand on 1/2" gap is not going to stay there.
Maybe that is OK for you .... if you want it permanent point it .... sand & cement (slow but cheap)
or use a brush in Polymeric mortar slurry .... brush it in, hose it off .... simple.
