Regular Tune up, spark plug changes?

Years ago, a car is supposed to get a tune-up, with changes to the spark plugs, on a regular interval. But there doesn't seem to be such things any more.

The regular maintenance is oil and filter change, fluids (brake, transmission, radiator), brake service, etc. How often should spark plugs be changed in newer cars now?

Whatever the manual says.
You can do them early if you want to do "preventative maintenance"

100,000km would be typical for most. If you car is high performance, maybe at around 60,000 - 80,000km

My Grand Cherokee lists 10 years or 160,000Km for spark plugs.

Yes. Consult your Car Manual.
Each Manufacturer is different (I'm guessing)

Not just manufacturer, but model/engine/options.

It's so dependant it's hard to say. For example on my car the manufacturer suggests every 60,000km for spark plugs, which is a bit excessive (you know its a bit much when the dealership recommends waiting a little longer haha). But honestly spark plugs are so cheap and easy to change (again car dependant) why not change them if you can't remember the last time it's been done.

IIRC many makers adopted the 160,000 km interval for main stream vehicles like over a decade ago, no??

So far, 2001 Honda Civic, 273,089 km - still using original plugs and wiring.

Nissan claims like the CVT Fluid, the Spark Plugs on my 2015 Nissan Murano SL AWD are lifetime.

Besides I was told it's a PITA meaning it will be expensive to change the plugs on the VQ35 engine. Both are estimated around $350 each.

Sometimes when a manufacturer says "lifetime" that can simply mean it's rated until the warranty is over. I'd probably check the Nissan forums and see what other people do or if there's any issues with running them. I don't see how a spark plug can last forever. Fluid in a closed system would make more sense.

If you wait too long, spark plugs can sieze up or cause thread damage when removed. Seen it too many times.

I would remove every 50 or 60k to inspect.

Run of the mill atmospheric engines have almost universally had 100,000km+ spark plug intervals for decades now. However you'll still find that many modern-day turbocharged and direct-injected engines have spark-plug-replacement intervals that are much shorter--typically somewhere from 60-80k kms. ...I just realised I'm saying nearly the same thing as booblehead, lol.

That's great but how much fuel would you have saved by changing the plugs when Honda recommended them to be changed?

Fuel economy hasn't been a problem and the car starts like a dream every time. I'd be more concerned if the injectors were dirty. Thanks to Costco gas, the occasional injector cleaner and we're rocking.
