It depends a bit on what kind of connections your audio interface has.
If we assume the classic Focusrite Scarlett or Steinberg UR242, then you have two options:
--> XLR or 6.3mm jack.
As far as the cables are concerned, there are very different qualities from different brands, but if you are not recording sound in the studio, I would simply use a rather cheap robust cable, e.g.:
BOSS (Electronics) BIC-10 Instrument Cable (3 m)3m length should be enough, but you'll have to see for yourself.
