[But is technically limited only by the max size of an ext4 filesystem.]
Not really, since the Pi computers support the SDXC standard, the max is 2TB. The ext4 filesystem can handle much larger, but 2TB is largest card the SDXC standard supports (after that it goes to SDUC, a future standard that I believe uses a different connection with more contacts).
As DougieLawson said, there are no 2TB micro SD cards available yet (1TB is largest at time of post), but when they are available (legitimately) they should work. Note that in models earlier than the 3B+ there's a bug in the bootloader that prevents the system booting from a card larger than 256GB (that's what I've read anyway, I have not tested it for myself), but the Pi4 should be good with cards up to 2TB.
To format cards larger than 32GB for use with NOOBS, use Fat32format GUI, available from the following site.
Again, that's only needed for NOOBS. Writing a Raspbian image
will overwrite everything previously on the card, so prior formatting or file-systems don't matter.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
