I personally avoid plastic where possible, some rabbits are chewers and can get blockages from plastic parts if ingested. Here's some pics of chewed plastic parts and toys I've posted previously. For the toys in your first post I think they are safe provided there no chemicals involved, especially wooden cubes, balls, birch or appletree logs, birch or pine tunnels for hamsters work great too, I've never tried pinecones but read that they are lots of fun too but if you are going to buy decorative make sure they are free of chemicals. Not sure about wreaths depending on the size and also not sure about bamboo, I wanted to make a few bamboo toys as well but find some conflicting info so not sure if it would suit rabbits. Willow sticks are great and also they sell small bridges for hamsters they can be used as chewing toys as well, I have larger hanging bridges for rabbits as well but they are more expensive, they are great. Pine hide houses are good they love chewing on them, but one of them lost one piece on the back and I found that they are attached with tiny wire which can harm my rabbits so I fixed it with a proper screw.
