All they do is slightly improve fuel efficiency; but they cost more to buy, and cost more to maintain. I had to dump my first hybrid because I couldn't find anyone to fix it.
The way to think of it is that a hybrid (both traditional and PHEV,) has more parts than an ICE car, which has more parts than an EV. It's more things that can fail as the car gets old, and more things to pay for when the car is new.
Edit: I should add that hybrids were good for automakers to dip their toe in the water for electrification: IE, get the supply chain working and get institutional knowledge. But, that ship sailed 10 years ago.
Hybrids cost more to repair, but much less to maintain. Hybrid brakes can last decades, and their tires and suspension wear is very near an internal combustion engine. However, the added complexity of a hybrid powertrain almost always makes engine repairs more difficult and therefore cost more money.
