It's not that this can't be done, but common training and certification are key. It's very different than refreshing the cabin because passengers do not need any training to fly (unless you call the safety briefing training).
That said, there have been some radical redesigns to cockpits that have preserved common type ratings. The 737NG cockpit was wildly different from the 732 and yet had the same type rating. There's a new 757 cockpit upgrade that replaces the majority of mechanical gauges and indicators with large LCD screens. But it takes a lot of careful attention to detail to make sure that a 757 pilot accustomed to the original cockpit can fly the new cockpit with minimal or no retraining.

It’s a good question because with certain amount of use things can definitely wear out. I remember seeing pictures of MD80/DC9 flight decks where the control yokes looked disgusting and totally worn out/dirty.

Seat cushions and covers get changed as they wear out. Either on the line or during checks. And the seats are repaired whenever components break. The two places I worked heavy check at both had seat shops. They would usually take the seats at the start of the check and do a detailed inspection and repair them. They were both in house c checks, I’m not sure what would happen an mro. it would depend what the customers work cards say and to how detailed they get.
As far as the interior, moonmat was typically changed at c check, or the carpets were cleaned if it has it. And damaged/worn linings or panels may be touched up or repaired. A lot of the time it depends on the operator, things can be worn in appearance but be perfectly serviceable still.
Where I’m at now, a light cleaning is scheduled every couple days I think when it comes through a hub. A more detailed cleaning happens when they go into the hangar for lighter checks and at the end of heavy checks.

I don’t know where the name came from but it’s the only thing I’ve heard it called, it was probably a brand at some point. I googled “moon mat aircraft” and the name showed in the first site description, but I couldn’t get it to open. Other sites came up for the same kind of flooring but they didn’t use that name. I saw coin mat on there, which describes it better because of all the coin size circles all over it. It has to get peeled up to remove floor boards for access during heavy checks and new stuff usually gets put back down from what I’ve seen.
