If you need to paint it, check the instructions for paintability;
it's written right on the tube. Acrylix latex is paintable, GE
Silicone II isn't, and others depend.

===> Yup, as I said, GE Silicone II would be great for that as
long as you don't want to paint it, and prepare the area before
I think if it were me, and I've done this, I'd use the
Painter's Acrylic Latex stuff though. For one thing, it would
show later on without a doubt if the gap opens more and make it
easy to determine later on if something were wrong with that wall
and maybe needed to be looked into.
It's probably just minor stuff, but ... best to be sure.
Or, you could mud, tape and mud it, then sand it out, if it's
a wall that matters for its esthetics. That's the usual way to
fix something like that, but takes a little more work and time.
: Any thoughts on this would be most appreciated.
I have successfully used caulk. The hard part is that it doesn't sand
well like spackling. It takes several iterations and use a sharp blade
to slice off the excess carefully and it looks OK. Other than that it
works fine. I have a spot where I have plaster which I think was put
on a heating duct. If I just use spackling it will crack again the
next day, and get progressively worse.
