Do these need to be replaced if they're regularly lubed and checked. If so, how often would you change them and would you just replace the cables, or the housings as well ?

Not unless shifting goes in the tiolet and routine adjustments can't cure it.The casing loop at the RD is the one that may cause the most trouble and it's a cheap easy changeout. Too much lube is bad especially in cold weather. I don't replace cables unless they are frayed, ginked, or otherwise hosed.

Of course, your definition of "regular" could vary. I do it at least once a year on bikes I ride often. I've done this since I had problems shifting one morning at the beginning of a 150 mile planned ride. Several miles into it, the rear shifter jammed, and I could not get it to work at all. So, I sent back home. I discovered, after a lot of investigation, that the shift cable had frayed inside the Ergo shifter housing so badly that the cable essentially locked up. It was a mess. Since then, I don't risk having rides ruined, so I change them out periodically.

Your definition of "regular" could well depend upon how much you ride, what you want to spend ($ and time) doing maintenance, and how much you want to avoid having rides ruined.

I follow the manufacturers' recommendations on lube. I think with Campy cables you don't lube. With generic cables I would.

I get about 5000-7000 miles on Shimano STI shift cables. I guess it depends on riding conditions, rain, dust, etc. They are so quick and easy to replace I don't bother pulling the cables, lubing, and re-installing them. I might do that on the short one back at the rear derailleur but normally I just replace the whole set, cables and housings.

It's pretty flat where I live, so it's not like I'm shifting all the time, but I've found that they should be changed every 20-30K miles (Campy) because by that point something has gotten kinked or frayed. YMMV
