What Gecko should I get?

Hi! I am interested in finding a gecko to keep, and am needing assistance. I have an 11 gallon vertical tank, specifically the Zilla Tropical Habitat starter, and I am wanting to pick the best option as far as geckos to keep in it. I am new to keeping my own reptiles, but I have volunteered at my local zoo where I assisted in creating diets, misting, and general care of various reptiles. Essentially, I don't know exactly how to start keeping a gecko, but I am more experienced once I am settled in, and have resources for further assistance. I have looked into various geckos, specifically crested, gargoyle, and chinese cave, but from my understanding these geckos require more space than I have available, and I of course do not want to give the geckos insufficient space. If anyone has any suggestions for a gecko that will thrive in a smaller vertical tank, and one that would be on the more beginner-intermediate keeping difficulty, I would greatly appreciate it.
