I used leftover particle board that the builders discarded. Been fine for 8 years now.

As long as you have a roof you don’t need anything special. OSB will last up there. You could go for a smooth finish to prevent splinters maybe. I screwed mine down and it has lasted over a decade just fine.

Yeah...but there's a wide variety. 3/4 inch pressure treated? Or just cheap 1/2 inch?
You need more than 1/2 inch for a floor. 3/4 Advantech will work
edit: I thought you meant for living space. 1/2 inch plywood or 7/16 OSB will work for storage as long as you don't overload it. If you do that the joists may fail if the flooring doesn't.

I've always used plywood...has anyone used this stuff before? It seems like overkill.

1x12 ponderosa pine. Cheap, strong easy to cut and you can get 8’ boards that you can carry into the attic

are you "finishing" the attic or just want something to walk on? If it's the latter, just use sheets of plywood or even OSB. If you use 3/4" ply, you're not stepping through that as long as you're alive. If you want it to look really good, I'd probably use tongue and groove planks.

I covered the attic over my garage in that Attic Dek plastic decking. Really like it. Bought a house and found the previous owner had poorly covered this space with 3/8 plywood that would crack under very little weight. My garage joists are 24', so I needed to keep the decking as light as possible....the Attic Dek helps.
Think it comes in 16" and 24" spacing so if your joists are non-standard you are out of luck without a lot of prework. Best think about them is accessing anything underneath them easily. I reran garage door sensor wiring and I could see where I needed to go (through the grids) and could get to it easily.

Yeah...I didn't think about 24" joist spacing and the issues that can cause if your plywood isn't thick enough.
ETA...accessibility to wiring is another plus.

OSB will be fine. Half inch or better.

a lot depends on what ceiling joist you have- however IMO we all tend to put too much in the attic and for that reason I would use nothing less than 3/4 inch ply
Look for damaged ply or damaged floor underlayment and negotiate a cheap price with the manager ( you are likely going to have to rip it to get it upstairs so damaged ply can save a lot of money
If you live in a new neighborhood talk with the contractors and scavenge the scraps. I know someone that did this over a period of weeks, one day super drives up with a load of scraps - jumps in the attic with friend- and says "Let's finish this project!"
