I think we're going to see the the Algerians be killed in Algeria more than anything else. Algeria was administered by the French as part of France proper, and I'd imagine a lot of the natives there would revolt like otl, and France probably would kill a lot of them to make space for French speakers.
But I'd agree that French Jews probably would have a terrible time in Action Francaise, it's just that it wouldn't be 'millions of people'. Only war in Germany would wrack up that number otherwise.
I do wonder if we'd still get something like Israel popping up despite no Nazis bc of Stalin. A more severe doctor's plot ittl would be a good catalyst for it, and if France goes to slaughter their own Jews I could see a mass exodus of Jews to Israel as they're scared. But I have to admit I'm not too well versed in the history around this, so yeah. I think an Arabian Palestine would be just as interesting.
