You're always going to have weeds. Those seeds are going to blow in after you lay down the mix. I wouldn't judge soil amendments on the basis of which have more weed seeds. That being said, compost responsibly made with garden and food waste is hot-composted (ask them) and, if so, will be largely weed-free.

Is this for edibles? If so, you might want to avoid compost that includes sewage sludge, which often has higher levels of heavy metals.

Right now it's just for flower beds around the house; eventually I'll get some veg. beds together, but probably not with my first batches of dirt :). I know plenty of weeds and bermuda will come in, I just hate to pre-seed it LOL. Thanks!

Probably any of those will work just fine for general soil amending. Compost made in a large commercial operation goes through a hot phase which generally kills weed seeds. If I was you I would go inspect the stuff first to see what it looks like. Is it sifted or chunky? Does it smell fresh and earthy or putrid (indicating it is not fully composted)? Do you see any debris like bits of plastic, rocks, masonry or glass? Is it soaking wet and drippy, or light and fluffy? Then choose based on quality and price. At this point, the improvement of adding ANY compost to that poor soil is far more important than which compost you use, as long as the quality is OK.

Either one of those places members of the United States Composting Council, or subscribe to the standards of that group? Tox has outlined some very good simple tests to use to determine which compost to get.
