It’s a Cellar Spider in family Pholcidae. https://spiderid.com/spider/pholcidae/ It’s probably in genus Pholcus. A common name for them is Daddy Longlegs. We don’t use the name because it is also used for a different type of arachnid ( Opiliones) and an insect (Craneflies). Your spider is both an indoor and an outdoor spider. I don’t know if they are capable of biting people, I haven’t heard of it happening. Even if they can, the venom isn’t medically significant.

Yes. They are in class Arachnida > order Opiliones. Spiders are class Adachnida > order Aranae. We don’t call them Daddy Long Legs because that common name is too common.

As you noticed, the lack of separation between tagmata (segments) is an important difference between the spiders and opiliones. Spiders have a narrow tube, the pedicel, between the tagmata. It carries the blood, nerves, ducts, GI tract, and doesn’t leave room for solid food to pass.
That’s why spiders have to drink their meals.
Opiliones get to eat solid food and chew it a bit because it can pass through their body.
They are interesting animals with an unusual ability to scale smooth vertical surfaces.
