Corgidogz is right (and I'm a poodle and cocker spaniel man!). A corgi is a tough little thing and really no trouble. My inlaws had them for many years.The only 'vice' one of theirs had was she hadn't forgotten she was a cattle dog. Cattle dogs drive cattle by giving the cows an occasional nip at the heels. This bitch would hide under the settee and, seeing the ankles of a visitor passing at a tempting height at nose level, would sometimes mischievously dart out and nip at their shoes then dash back under the settee again !
Sorry,but all dogs are capable of biting. You have to consider whether you want one which has strong jaws, and is of a breed originally bred for biting and fighting, in your house when there might be children about.Think of the consequences.There ain't no such thing as a killer King Charles or poodle or corgi (of either kind)
As to barking, the dog has to be gradually adjusted to the idea of being left.Then it won't get a sense of anxiety and so bark (though some breeds are always vociferous , regardless e.g Keeshonds ).Having an older companion dog, known not to bark when left, can help but you may equally end up with two barking all the time !. Make sure the dog has something to amuse it, toys etc. (I have left the TV or radio on low for mine in the past,since they learned that that meant I must be coming back: it is, after all turned off at bedtimes and when we go out together, but that may be going too far! )
