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.

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.
