Hi Abbey,
I like the options you have provided, and I think it's great that your database offers them! My institution is part of a large university, and our database does not have such options. We've considered not using titles at all unless someone specifies them, but this makes it difficult if an individual values being identified in a certain way. I like the "they, them, theirs" that Janice referred too. You could perhaps just ask a person which pronouns (he/she/they) they prefer rather than listing all the options you have provided. I think it depends on which information your volunteers will be most likely to provide, since you want the information so you can use it. Do you think people are more likely to check a box in a short list, or do they prefer more options? Perhaps your database company could provide some insight on that question specifically.
I also just like the family inclusive language paper from the Incluseum blog for training volunteers and staff, so I'm including it here!
