I'm uncertain why you think you've imagined it. FAT32 supports 2TB volume sizes for 512byte sector media. Repairing them is fairly straightforward, although it takes longer than with a journaled file system. While not yet cross platform like FAT32, f2fs is shaping up to be a better alternative for SD and USB flash media.

Great, you have something that's able to work around the file size limitation, in which case use FAT32.

Right, your user choice is being limited by what is essentially proprietary hardware - the TVs. But also unfortunate timing, in that there haven't been significantly better alternatives to FAT32 that address resilience, volume size, and file size limitations.

If the TVs mount either filesystem read-only, I'd be more tolerant of their use for this use case. And maybe they do this already. Offhand I'm not thinking why a TV would need mount media as read-write.

There are still open questions on its legal status as indicated in your own link.
