Don't use XYZ. Because of recent $1 sales on XYZ domains, they're being snapped up by spammers, and there is so much spam coming from them that one of my most effective spam filters is flagging anything from a .xyz domain. I don't think I've ever had a false positive. I have the same issue with spam from .top and .pro TLDs as well. IO should be fine. There's enough legit tech companies using .io now that it shouldn't have too much reputation risk. Maybe start out with the .io until you're generating enough revenue to drop $1.5K or $3K on the .com.
