macOS Sequoia refused to mount a FAT32-formatted microSD card from a security camera because the partitioning wasn't compliant or something.

I installed Windows 11 in a VM, and it mounted just fine in there.

Precisely to my point. On OSes that don't arbitrarily filter which filesystem you can use, it is a solved problem.

It only feels like an unsolved problem because some OEMs benefit from the fragmentation.
