You couldn't even buy MicroSD Express cards larger than 256 GB until well after the Switch 2 release. I don't know that even if Nintendo wanted to offer larger storage, if they would've been able to source the chips needed, if nobody was making them.256GB feels so small these days that I ended up buying a 256GB Express SD so adding both together, my console has around 500GB total (379GB free). So no, not really.
I did buy a 512GB Express SD card, haven't used it yet.
It reminds me of Apple's Mac Book Neo, it has 8GB RAM and 256GB SSD. It's like both of them are including the bare minimum as they know it'll sell.
Anyways, I think 256 GB with expandable storage is pretty reasonable. Many (or even most) devices sold with 256 GB storage don't have that. You'd be hard pressed to find any smartphone nowadays with expandable storage that isn't a budget smartphone and those only give you the bare minimum of internal storage and pretty much expect you to always use a MicroSD.
Personally, I'd much rather have a small amount of internal storage (even just 32-64 GB) with the option of a MicroSD, than a larger (say 512 GB or 1 TB) internal storage without that option, since popping in a MicroSD is so easy and you're able to upgrade it as your storage needs grow.
