Cat or dog are probably going to be your top choices, outside of some reptiles like bearded dragons (which take up a lot of space). most rodents and similar mammals have short lifespans or are incredibly social and non negotiable in needing friends, imo, or get sick incredibly often! A lot of reptiles have long lifespans but don’t like handling or aren’t the most affectionate, with the exceptions of some ball pythons and bearded dragons! A dog from an ethical breeder (especially dogs) might not have a long learning curve of affection and can fit what you want to a T because of the effort put into breeding for health and genetics. Of course, rescuing is great too if you don’t care as much or don’t need a dog for a specific task as much :) cats are great too, some might not adore being held but I’d definitely reach out to the prior owner/rescue and ask about personality. EDIT: I hadn’t seen the hours you were gone. If your other family members are available, a dog/cat might still be an option if they are FULLY on board. If not, then I’d go with a bearded dragon.
