I feel for anyone who feels unsafe in their homes and communities. I can't imagine the weight of the decision to uproot yourself and your family to emigrate to another country for reasons beyond your control, especially discrimination.
It's worth noting, though, that this article seemingly goes out of its way to obfuscate what qualifies as anti-semitic acts.
"This kind of expression is no longer coming only from the extreme right, but also by the far left — and while it’s doubtful that it’s always antisemitic, anyone sensitive can feel that it’s never far away in certain discourse,” warns Wieviorka.
Palestinian solidarity is not anti-semitism, and there are abundant indicators (from this article and its links) they're being conflated in France.
All your sources rely on the same primary source: the interior ministry. And I don't see a breakdown of the acts. In a number of articles, graffiti of stars of David across buildings in France was categorized as anti-Semitic, which seems really weird to me because they weren't defaced or altered in any way, just stars of David. On its face I would think that was...pro-semitic.
Either way, I'm not denying there has been an uptick in anti-Semitism and that any and all anti-semitism is indefensible. But there also seems to be a deliberate effort to embellish the narrative by treating anti-Israeli or pro-Paletinian acts as anti-Semitic. Then people react to that narrative with fear, and their fear is used to further credit the narrative.
The insidious part is that these stories treat the narrative as support for Israel's ongoing aggression.
