You said this is extra gear you have yet to find a place for. That means you already have a lot of stuff successfully stored so these suggestions may be already taken by something else.
I put spare life jackets under the ice chest bin, under the after dinette seat. I only carry an extra, extra large (in case I get a rotund guest), a couple kid sizes, and a couple pet life jackets there now. At one time I had 14 life jackets, clearly to many. Leave the holdall at home. If that space is taken, slide them under the after berth deck, two on each side. You probably won't need them often. You normal PFDs will do most of the time.
The tool bag is probably to large. I only carry a small one I lay next to the compression post under the table. It is easy to tell anyone on board where it is and what to get me. I have used very few tools out on the water. I leave more home each time.
I carry two anchors, a claw and a danforth, on the bow. The Claw is in a PVC pipe holder and the danforth in the anchor locker. Both anchors are tied to either end of the same 250' rode. When I have to deploy a stern anchor, I do so from the bow and walk the rode back. I frequently use the stern anchor as the primary and only anchor. Retrieved rode goes right into the locker.
I have 200 ft of spare lines in the bottom of the battery compartment just behind the sink counter.
My hose is coiled and slipped under the dinette floor. I have a sting tied to it so I can retrieve it when needed. The wash muffs go in the port fuel tank compartment.
My buckets, I have three, are in the rear of the after berth compartment. They are full of cleaning and polishing supplies. They don't get used much while underway. I think they will go into the tow vehicle in the future. One bucket is useful and could store lines or signal shapes.
I only carry the flags I am going to use. The others are in the garage.
My foghorn goes in a shelf I made in the head. It is not used that often but still available if needed.
The spare winch handle lays on the after deck, under the mattress, next to the head.
The sail covers are just rolled up and placed in the Vee berth in a clothes basket.
I only use 4 fenders normally. They are tied to the after cleat and the three lifeline stantions. When underway I just pull them up and let them lay on the cabin top and the cockpit edge. They stay there fine and are ready for instant deployment. My spare 2 are with the extra life jackets. When trailering I tie the 4 together and hang them on the front of the pedestal. They are now in the garage, waiting to be cleaned from the last trip.
I leave the cockpit cushions out at night. They get wet but I wipe them off in the morning and then use the wet rag to wash down other things. It works okay. They will get wet in a hard rain and are very hard to dry. I may leave them home next trip.
I have only made one day trip so most trips we just make the bed and it stays made the whole trip. We sleep crossways at the front of the after berth. Thare is plenty of room and it leaves a lot of storage behind us.
Our clothes and towels, etc, go the in the ice chest bin. I figure it is drier than anyplace else.
We use two five day ice chests that sit on the aft end of the vee berth. The one forward of the dinette seat is full of frozen quart bottles of water, green tea, lemonade, and juice. The other, forward of the settee, has our food and drinks in it. As ice is needed we transfer quart bottles and when they melt we drink the contents. One thing I found the last trip. I wrapped the heavy winter coat I had taken around the food ice chest. I was amazed how much better the cooler performed and held ice. I will be making insulated covers for them soon.
Other food stuffs and supplies go in two, three drawer plastic cabinets under the table.
That covers everything you listed, I think. Boy, you should see my list
