Tune-up is just a generic term for periodic car maintenance, so yeah, they still need a tune-up.
Cars don’t need points, timing, dwell, and condensers anymore. “Lube jobs” are generally a thing of the past.
Tune-ups mostly consist of oil changes now. I still do my own, in addition to tire rotations. It keeps me in touch with longer term needs, like brake pads. Then there are accessory drive belts, spark plugs, nowadays stretching to 100k mile intervals. Also keep an eye on transfer case and transmission oil. Manufacturers have actually reduced those service intervals to keep high dollar repairs at bay, and save their reputations.
Ford was especially bad with transmission failures. My son’s Focus recently had a transmission replaced at $2500. He bought it used and the service history was unknown. Another Focus we owned from new made it to 135k miles until it was lost through an accident, and I have an Expedition with 205k miles running strong with regular maintenance.
Just don’t get a tune-up from a cop.
