I'm wondering what you decided to do?
I would do a hügelkultur. If your not keen on having them invade your yard you could do it a few feet from the fence line enhancing your privacy. I wouldn't use the pallet wood, but all other wood is fine for a hügelkultur. Even the very poisonous oleander is safe to use. (composting is pretty much the only safe way to get rid of oleander)
If your still not sold on hügelkultur, If you want a garden you could go for a hugel beet. I do what I consider a hugel beet two different ways. One is the traditional raised be with a twist. I have raised beds that are 2' and 3' high. I load the bottom layer with the largest wood I have that will fit in the space. Then I fill all the crack and spaces with native soil. Then I do a layer of smaller wood, branches, etc. fill gaps with soil. Stuff yet to be composted ( kitchen scraps, tomato stalks, leaves, what ever I have that will brake down) Then wood chips, soil. The last 1/3 or at least 12" I use compost and organic soil.
The other raised beds I have I dig 2' into the ground where I want my raised bed to be. I line the hole with one or two high cement blocks. I do the layers the same as above. Besides putting your largest wood on the bottom and using soil, compost, or something to full the gaps, the layers don't matter. Basically use what you have. I live in a super dry area, so the biggest benefit for me has been water retention. It's also allowed me to build more garden beds with out spending hundreds of dollars on soil to fill the beds. In your case getting rid of a huge pile of wood in and earth friendly way. I'm totally sold on this type of garden bed. Hands down the best, most amazing garden I have ever had. lush veggies that produced like crazy. (The gopher thought so too. If you decide to go this rout and have gophers, or moles in your area, spent the extra time and money to line the hole, or bottom of the raised bed with hard wire cloth. Doing it after the fact is no fun.)
I also like to add wood and compostable stuff to holes I'm going to plant trees in.
Good luck to you. what seems like a big messy pile, and no matter what you decide to do will be a lot of back braking work, could also be a blessing in disguise.
