Quality SD cards have perfectly fine write performance. They’ll cost two or three times as much as the cheap knockoffs everyone else is getting (which were the reason many phone manufacturers sabotaged features like adoptable storage because they slowed the entire phone down to a crawl), but if you buy from a real store and pay attention to the markings on the card, SD cards work absolutely fine.
I don’t see why you’d need them these days (my 128GB phone currently has about 40GB in use and I don’t think I’ve ever filled up my 64GB Oneplus One either) but if you do want them, SD cards are perfectly fine if you do your research before buying them.
As for headphones: some people like the DACs that phone manufacturers used to use and don’t want to charge Bluetooth headphones. For years phones had unused blank space in the that could’ve been used for a headphone jack, but these days phones are getting larger batteries so I’m not sure if it’s still as easy as that.
