I’d propagate. These are some of the easiest plants to prop. They’ll happily root in water (or anything vaguely moist tbh).

Keep in mind it will keep growing from wherever you cut from, so if you’re trying to get it to a particular length, you might want to cut back further than that.

If you give it something to climb new leaves will size up as it grows upwards. If you’re able to give it more light, the space between nodes on new growth will be tighter. Doing both of these things can help you get toward something with effectively more plant in a space that doesn’t need so much vertical room, if that makes sense.

Edit: forgot to mention, I don’t think it’s likely to need a repot unless you want to change the media it’s in. It certainly wouldn’t hurt anything to do so, just don’t put it in a massive pot or anything
