It's definitely not that cut and dry. Here's a paper with a good breakdown of safety comparisons: https://www.sciencedirect.com/science/article/pii/S2352152X2...
Tldr: while sodium thermal runaways are less dangerous than lithium, they are more likely to happen, and in particular charging a sodium battery to 100% SOC makes thermal runaway significantly more likely than in LFP batteries.
It's true that things like puncture or short circuit are much much less dangerous than with lithium. That is a big part of why the increased thermal runaway risk gets overlooked.
