3.5 jack port is definitely not more durable than USB-C. If you have good headphones, the change that the 3.5 plug is gigantic in length and the cable thicc AF which causes a lot of stress in the plug due to very large leverage. Additionally, I prefer to use the DAC integrated in my headphones rather than using the low quality tiny DAC in my phone. And in digital, the cable thickness does not matter really.
Very few people are plugging their large headphones into their phones though. For a more reasonable pair of portable headphones or IEMs the size of the plug isn't a problem.
But congratulations, you have hit on my biggest audio pet peeve! DACs matter very little these days. Anything talking about DACs and not the DAC/Amp stages is marketing BS. Even dirt cheap DAC chips will acoustically transparently convert the digital signal to analog in audio frequencies because it is so basic to do. DACs on their own are useless for audio anyway, what really matters in your audio signal is the amp circuitry after the DAC that applies gain to the signal to useful levels as the choices there do make an acoustic difference if the design is poor.
What makes you think the DAC/Amp in your headphones is going to be better than the one that is built into the SoC of your phone? I don't think I've ever seen any measurements of headphone DAC/Amps.
I learned that from my father, who mostly listen to music from his phone using external headphone amp for his bayer dynamics studio headphones, or uses digital out (via Bluetooth) and let his other Bayern dynamics active headphones do the DAC. He is sure that he hears the difference, but of course that could all be in his head alone. I myself am not a hiFi enthusiast, I only find the tech behind it very interesting. (I listen to music using airPods and in my car using CarPlay, sorry iPhone user here, but thinking to migrate as soon as my iPhone X becomes unusable) But given my interest in tech, I appreciate the explanation, that cheap DAC chips are very good as well, these days.
