Am I missing something? Isn’t this why we use AC power over long distances?

No, DC is for long distances

Yeah I started reading up on it more once I got thinking about it. Looks like AC was easier in the past, which is probably why we’re standardized on it for local grids
yeah, AC won during the current wars in 1900, mostly because efficient transformers were only available for AC at the time.
nowadays DC is often used for high-power long-distance transport though.

No such thing as a DC transformer. Transformers rely on generating a changing magnetic field and for that you need AC.
interesting piece of trivia: In 2003ish, there was a major power outage across the northwestern US and much of eastern Canada. One major issue was that the grid became desynchronized so resynchronizing was a major problem they had to solve to bring the grid back up. The province of Quebec uses high voltage DC lines (and also massive amounts of hydroelectric power, but that's a conversation for another day) so they didn't have that same problem and had returned their power to normal long before the rest of the region.
