Wired is more efficient, you can pick it up and use it while charging, and the cable usually comes free with the phone. What is the point of wireless charging pads?

It is more inefficiënt, yes. But why would it reduce battery lifespan? Is it because of the added heat from the wireless charging coils? My battery probably stays cooler with wireless charging then using the wired turbo charger. Which is more and more standard these days.
All our modern charging methods are really bad for batteries. Wireless is inductive which means the charging voltage is noisy and very variable, this means heat and that stresses the batteries faster. But, wired charging with PD uses really high voltages, which are sometimes way too fast. Also stressing the battery. We’ll see what comes of it but the recent couple of phone generations are prone to be the ones with the worse battery life expectancy.
Companies are usually aiming for 80% at two years time. That means that a phone that barely survives a day when new, will not make it through the day two years after. As the battery loses capacity, it requires more charges per day, accelerating the degradation.
Here’s iFixit assessment of wireless charging.
This is MKHB on why heat hurts batteries and how companies try to fight back the damage of fast charging.
Wired turbo chargers are bad as well. However, although I don’t know about iOS, Android lets you plan your charge cycle. That makes my phone take about 8 hours to charge while I’m asleep.
Or you could just not use a fast charger and not worry about that. Either way, you’re moving the goalpost. Not all phones support fast charging and not everyone has a fast charger. I’d wager most people charge their phones with lower power (15/20w more or less).
