Why is the left opposed to school choice?

[Famous Mortimer]

All schools should be the same. If we're in a situation where choice matters, we're doing something wrong.

Because the left doesn't understand its own position

I would agree with this. The left has no position other than "give teachers more money" because it's in the pocket of the teachers unions.

The right is pushing for deregulation, decentralization, and privatization of public schools because that's their position for everything.

The left should be pushing for regulation and national standards in addition to extra funding but, of course, teachers unions just want a raise regardless, they don't want it to come with any oversight.

How would you propose doing that? Geography and demographics are both extremely diverse. I'm not sure one could devise a one size fits all school outside of having every student access the same virtual classroom. Should physical schools all close? Even then the backgrounds of the students would be sufficiently diverse to prevent students from equally benefiting from identical virtual classrooms.

2+2=4 everywhere. The allies won WW2 everywhere. I don't know why demographics would matter. We need a unified national curriculum. There's no reason Butthole, North Carolina needs a special curriculum different from Chicago.

Opposition to standardized testing is illogical. Regardless of if you have a national curriculum or not, you have to have tests to see how the students are doing. If it's a bunch of different tests with different standards, the scores would be meaningless, or they would have a meaning which no would could understand.

Again, it's simply that teachers unions (which like all unions, advocate for their members, right or wrong) don't want anything that could lead to teacher accountability. They just want raises regardless.

Of course, it's fine for them to do that. That's their job. That's what unions do. Democratic policy makers should be smart enough to realize though that while it's a good policy for teachers union members, it's not a good policy for anyone else.
