Anne,
I am not a CG Aux member, but here is my experience of 15 years cruising the Northwest waters in my 22 cruiser.
I had a 22lb Bruce on the bow, with 30ft of 1/4 chain and 300ft of 7/16in nylon three strand line.
I carried a 13lb Danforth anchor with 30 ft of chain and 300 ft of line in the cockpit.
The line and chain were carried in a 'milk crate' with a plywood lid, in the cockpit and the Danforth was hung on a SS bracket from the stern crossbar.
This anchor gear provided two complete anchor systems, with the Bruce being my primary and the Danforth used for a stern anchor, and as an anchor for soft mud, where the Bruce would drag. The Danforth was also a backup anchor in case of loss of the Bruce.
This gear was adequate for use from Olympia to Sitka, Alaska, and I used it for the 15 years that I owned my 22 cruiser.
On your boat for self launching, I would go with a Delta on the bow, and perhaps an aluminum Fortress on the stern. It is important to use 25-30 ft of chain, of a size to fit your windlass, and 250-300 ft of line, also sized to fit the windlass.
