I'm in the same boat, but stuck in HOA land here too. Got my 10'x4' finished last weekend but haven't dug it in, filled it up, or hooked up the drip system yet either. I think I'm going to put a small diagonal trellis on end for pickling cukes, a small vertical trellis setup for pole beans, a couple tomato plants, and then not sure what I'll do with the rest. I'm clueless when it comes to a garden, but hopefully will start learning fast.
I also want to build another smaller raised bed that I'll put between two of the split rail posts for a couple raspberry bushes if I can find the time too. The area right behind our fence is an open-space walking trail. They leave it "natural" which means we get a lot of weeds back there in the summer. I chop or spray the foot or so on the other side of the fence a couple times a year, so it'll be interesting to see how this works out.
Hopefully the added height will help with the rabbits, but I'm told my biggest problem will be when the raccoons find it.
Here's a pic before it got all snowy showing approx. where I plant to sink it in. I need to add probably another layer of side 4' boards though because of the slope.
