Fuses with "S" designation
Can anyone elaborate on the fuses with "S" designation? What is their significance, and why can't I find them advertised for sale anywhere?

I don't know what the "S" means but a regular fuse will work just fine. The cup cooler/warmer blew a fuse on our '15 GL and I went to a local parts store and bought a $1.25 fuse. Works perfectly fine.

On Maxifuse blades - the "S" designates "Slow acting".. so that in addition to amperage you this is "Slow acting" type as compared to non-marked "Fast acting" type...

The "S" designation on ATC/ATO blade fuses (not MAXI as those are the bigger ones) stands for silver contacts.
These are used due to their better conductivity over traditional brass fuses. You should not mix and match these fuse types as due to the dis-similar metals you can increase the risk of corrosion at the contacts. Silver fuses plug into silver sockets. While yes a regular fuse will work temporarily, however if you leave it in long term, you will end up with issues.
I'm sure they are online somewhere, but they are available at the dealer.
For further information you can reference Star Bulletin T-B-54.15/254.

Fuses with S designation
MBtech1098 has provided a very good explanation of the significance of the S designation on the fuse. Couple of notes to add:
1- The receptacle that the fuse plugs into also has silver. So, if you use a standard fuse, the use of dissimilar materials can cause galvanic corrosion and issues for the electrical system.
2- There are also some fuses with "N" designation, which indicates nickel. Same as those with silver, substitution is not recommended.
3- I just purchased a "5 s" from my dealership for $1.00. It is a hassle to have to go to the dealership, as opposed to a local parts store. But, not creating problems for the electrical system and potentially voiding warranty aspects of the vehicle is worth the hassle from my perspective.
