You’re definitely not wrong. Gray hydrogen currently is the most common source, which is a byproduct or an intended product of petroleum cracking. This also is probably a reason why most petroleum companies chose to research hydrogen in the 2000s/2010s rather than battery or other renewable technologies, since it fits nicely in their existing pipelines.
For storage, I’m pretty sure you can keep it at atmospheric pressure and temperature if space isn’t an issue, but to actually fit it in a vehicle you’d probably have to use one of the techniques you mentioned.
The Mirai’s issues seem to be that it was just a foothold for consumer hydrogen without anything really backing it. You could almost say the same about EVs/PHEVs 15 years ago and look at them now.
Honestly though, if we are able to scale up sodium batteries, grid storage and train usage might be moot. Ships could probably still use it as an alternative to diesel though.
