Terriers bark. I had a West Highland White Terrier (as well as a cat), neighbors had a miniature Schnauzer, and another a Bischon during my work at home years. All barked at times. Only one person ever remarked about it, so that probably isn't really a problem.
If I had to pick just one pet, it would be a cat because a dog sometimes needs to go outside (although, I did have a pee pad corner in the basement for "emergencies", especially as she aged).
Definitely meet before you adopt. My last 2 furbabies are from a large shelter with over 200 cats/kittens there, plus more in foster care. They pay for a vet visit during the first 30 days if necessary, allow you to "trade" once during the first 14 days if it isn't working (although it took a few months for one of the two to decide that I was okay, she's the lapcat now, but if you were really having problems....).
I have been adopting 5yo and older for at least 20 years, they have more troubles finding homes. A good shelter will match you with pets to better fit your household. I met 10 and adopted 2 of them after my last pet died at 15yo. from cancer. I definitely "clicked" with one right away, total disinterest from a few (nap time in one case, how DARE I), the 2nd was interested and cautiously friendly.
Enjoy your new furbaby!
