My understanding is that all models of Pi will read and write 32GB cards. I've certainly not had any trouble with the older Pi B+ models and 32GB cards.

Because beyond 32GB NOOBS is a pain. You have to format a 32GB partition to use with NOOBS on a 64GB or 128GB SDCard (and that's beyond the skill of novice users).
Looking at Amazon for the well regarded Sandisk A1 class cards, 32GB is cheaper than 16GB.

I cannot see why anyone would buy a 16GB card nowadays.
because I already have 32GB or less on stock (knocked off the RPi3Bs after USB boot enabled).... and dont want to spend another buck on a "cheaper" 64GB?
I would suspect it's not so much a "buy this" insistence, but more a suggestion that "the bigger the better", from a time when 64GB and larger were not so cheap, when the differential cost was much greater. Or it's simply "the minimum" which is needed to work well.
It's more that 64GB and above cards default to exFAT on some systems.
In addition, the usage may be simpler with all the data on a single disk.
Unless you are doing things the wrong way, the time for the backup and restore will depend on how much data is on the card, not how big the card is.
Back in the days of Pis using full sized SD cards, I ran a full Raspbian install on 4GB cards. It was rather annoying when Raspbian would no longer fit. I have also done a Raspbian Lite install on a 2GB card. I have used (once) a 64GB card for a Pi. Special situation. SSDs...generally around 60GB, though given current prices, my next batch (I need 3) will probably be in the 120GB range. The only HDD I use for a Pi is 314GB. That one has had an in situ upgrade to Buster and the Pi will be upgraded from Pi3B+ to Pi4B2 when USB booting is released.
So far does not seem to be the case for the other SD stuff I do. Maybe "doing things the wrong way" but I'm competing against others who are more up to speed on these things yet still lag behind. True of Piclone but In my experience not so with Win32DiskImager and most other SD utilities. Big card usually takes big time.
