Wiring an enclosed porch question

[Mking143]

Hi all,
I'm going to be hanging some barn pendants in my screened in porch, the power would be coming from an existing sconce on the porch wall, the switch is inside the house. The ceiling is open frame, and the porch is subject to moisture in bad weather.
I'm confused about what cable to be purchasing for this- the pendants are 2 wire plus ground- and whether I should be running this in conduit or liquidtight. I would be installing weather resistant junction boxes. but my main question is cable and conduit.
Below is a pic of the porch and ceiling. Thanks in advance.

I'd run it in conduit. I'd prepaint all the conduit a nice dark color or accent color. Surface mount would work well with timber frame.

I'd probably do the same thing. Surface conduit like Wiremold is probably less offensive than round EMT as it lays flatter and is rectangular in section, so it tends to blend better with exposed framing. EMT always looks sort of, well, industrial. And obvious.

OP: Try to bring it up inside the wall to the ceiling/roof if you can, so you don't have it on the wall. Might need a box where it comes out of the wall, and you can use NM inside the wall, but change to THHN or THWN inside the conduit.

PVC will hold up better in the damp than EMT [rust], easier to work than rigid. I'm thinking that Wiremold is for dry locations only.

They make plastic versions. I think the stuff I linked to above is plastic, and suitable for damp locations, but I didn't specifically check for damp.

You can do a very nice and neat job with PVC. They sell all the fittings and straps and boxes to really do a nice job if you know what you are doing. Easy to work with.

Even make your own custom bends, offsets, etc. Heat it evenly until soft, form to fit, cool with a wet rag.

I would also use pvc. Moisture isn't a big deal in that application. If you get enough wind that any of it gets wet then the house will have also blown away.
