Anchor rode and chain
I'll defer to others regarding a choice of anchors but encourage you to check out American Rope for the anchor rode and chain. American Rope offers a 1/2 inch 8-strand plait (braided) rope that is easy on hands and that flakes effortlessly into a container without twists or kinks. I use a 13 x 18 milk crate for 300 ft of rode and 15 ft of 1/4 inch stainless chain. American Rope will splice the chain and rope, and splice a 12 inch loop on the bitter end, for a few dollars. I found their quality and price to be much better than West Marine, Cabelas, etc. Their web site isn't easy to use but customer service over the phone was excellent.
