It's fair to say that between battery manufacturers cycle counts will vary. Like you said, sodium ion is a nascent technology with many new players, and improvements to battery technology could improve cycle count, but cycle measurement in absence of the DoD it was tested at makes it hard to know how durable the battery is under real-world usage. Li-ion and LiFePo can have insane cycle counts if you never go below 80%. To illustrate here's a diagram I found on the first Google result (though from 2017, batteries were worse then) https://www.researchgate.net/figure/Depth-of-discharge-versus-cycle-life-of-the-lithium-ion-battery_fig4_318292540 https://www.researchgate.net/figure/Depth-of-discharge-versu...
