In my experience, when a device says it only supports SD cards up to
32GB, it means it doesn't support xfat, which is how most cards 64GB
and larger come formatted. My own talking book reader/mediaplayer, a
Blaze ET, is advertised as only working with cards up to 32GB, but it
works just fine with a 256GB card after formatting to fat32, though
admittedly, it wouldn't recognize the card prior to the reformat and
even after reformatting, the player's built-in formatting app has no
idea how to handle cards larger than 32GB. In general, my
understanding that the only difference between SDHC(Cards in the
4-32GB range) and SDXC(Cards > 32GB) is capacity and the default
filesystem(Fat32 vs Xfat).
Also, a quick Google search tells me that FAT16 has a size limit of
2GB, and I'm pretty sure they don't make SD cards that small anymore.
The same Google search tells me FAT32 has a minimum file system size
of 512MB, and I'm not sure they ever made SD cards that small.
Though none of that is really relevant to the Pi since you won't have
any kind of FAT filesystem on the card once imaged. That said, I
believe most images for the Pi require an 8GB card(some minimalist
images have been shrunken to fit on 4GB cards, but that's mainly for
the benefit of those using an old card as even 32GB cards are almost
as cheap as the Pi Zero these days).
Form factor wise, the Pi uses MicroSD, and most MicroSD cards come
with an adaptor for a full-sized SD slot. 32GB MicroSDs are pretty
cheap, while the 64GB models are quite a bit more pricey and the 128GB
and larger MicroSDs are either non-existant or prohibitively
expensive(Even for full-sized, a 256GB card is 80 USD and full-sized
cards are usually cheaper than MicroSD). While I doubt a 64GB card
will give you any problems, you might be better off with a 32GB card
and if you really need that much storage, just hook up an external
harddrive.
I know nothing relevant to the class questions.
All that said, you could probably use the card that came with the kit,
though it would be recommended to create a backup image of the card
before imaging with your chosen image, though someone else would have
to walk you through that process.
