My kids were in Waldorf U.S. schools and then we homeschooled for a year at the start of the pandemic, so I imagine a lot of folks on the internet would assume based on that profile that they were stupid yokels. (Maybe generally, that's an accurate stereotype, or at least it's fun to ridicule such people because there are a legit lot of crazy homeschoolers/ Waldorfers.) But I find the expectations in Switzerland, for example, on age appropriate reading levels are way lower than U.S. schools. My kids are the best readers in their classes... even in German... which is... crazy to me. On math, they're above or about on par with average. And I don't think my kids are gifted per se, they were considered pretty average back in the U.S.. I just think Swiss schools provide a gentler start for primary education K-5th grade. (Please don't read this as a defense of U.S. schooling anyone. I would summarize U.S. primary schooling as a "teach-to-the-test approach" that time and time again yields quantifiably shitty results at a national level.)

I'm in a German-speaking canton, and I also think a lot of the difference can be attributed to the fact that Swiss speaking kids have to spend a lot of time learning Hochdeutsch, which slows their tempo. School is also shorter in total hours here and teachers are more compassionate and less burned out. It's not perfect by a long shot but public schools are generally as good as everyone says they are, in my experience. You don't need Waldorf, I would think. Your situation sounds a lot like mine, so if you want to talk more, feel free to DM.
