What Tree Frog is this?

From the descriptions I've read I don't think the spots are mandatory, just extremely likely. They are also known to hybridize with American Green Treefrogs, Hyla cinerea, so you can get some in-betweeners.

The fatness of yours makes the Barking treefrog look most likely to me, but I don't really have any first hand experience with most of your natives.

As to the 'clingy' behavior, I've always taken this to mean- "I'm not currently being eaten, so I'm going to try to stay attached to this pink fleshy thing, cuz it could get worse". It seems to be a standard defense mechanism of all the wild Gray Treefrogs I've had to move from various dangerous locations (in front of lawn mowers, about to be squished in window frames, etc.). I don't take it as a sign of them being comfortable with me.

I've taken my two Hyla Cinerea's outside and have sat in a chair with both on my fingers, neither even attempted to jump off to freedom. In fact, one jumped on my shirt and just stayed there while the other walked up my hand to my wrist
