For some reason sd card slot is like audio jack, it's considered a thing for middle tier phones. Xiaomi have a bunch of them (various Redmis for instance), and Samsung at least used to, I haven't checked recently.
Sony seems to be the last manufacturer offering MicroSD slots in their high-end phones. (The last manufacturer that sells phones in the US, anyways.) They also include a headphone jack!
Samsung ditched both of those features in recent years.
I kind of hate sony, but in this instance they seem to be less shitty than everyone else.
