For such as I, is there a relevant distinction between IPv4 and IPv6
except address space?

Not really. Bandwidth is determined by your ISP.
I find these helpful:
man interfaces

None if you only use email and the Web.

If you type "ip address show" (can be abbreviated to "ip a" and see any
line with "inet6" (not "inet") giving an address with "scope global"
(not "scope link" nor "scope host" then you are using it.
(You could still be using it locally over localhost or private addresses
but this is splitting hairs.)

You have described your network configuration before and I seem to
recall it is somewhat unconventional for the 21st century.
If what you
have works then I don't think you need to spend any time wondering about
IPv6 unless you specifically want to. You may even be using IPv6 on your
end without knowing.
If you do want to learn about it then even if your current provider
doesn't offer it, you can use it through a free tunnel, but it isn't
going to provide much except a learning experience.
Thanks,
Andy

This is not true in the general case for web since IPv6 will not have to
go through the possibly multiple layers of NAT that increasingly have to
be used by Internet access providers due to the shortage of IPv4
addresses. Such so-called Carrier Grade NAT (CGNAT) setups are slower
than end-to-end connectivity.
On average, IPv6 conversations with top web servcies are about 2ms
faster than IPv4 and have been for more than a decade:

However, given what I know of Richard's setup in particular (a USB
connected cellular dongle), he specifically is not going to notice any difference.
Thanks,
Andy

Richard isn't a gamer.
T-mobile's salesman was the only one that:T-mobile offering varies by geographical region.
1. actually listened to what what I wanted to accomplish.
2. did *NOT* tell me I had no choice but a "smartphone"(sic).
He offered a WiFi Hotspot which I treat similarly to my old acoustic
coupler (the WiFi portion disabled by software ;).

It may be available in yours on request, rather than by default.
It's probably worth asking, if you want to learn something about
IPv6. Some of what I learned about IPv4 turned out not to be
transferable. YMMV.
In Germany, IPv6 just works on their cellular network.
I know this from roaming there from my home network in Ireland.

You need to check in your router too, if it is enabled. You also need
to know (ask them) if your ISP supports it (or it needs to be requested etc.).

"Available" may have been a poor word choice.
I was thinking in terms of:
1. what is supported by my existing hardware/configuration?
2. did I have an active IPv6 connection?

Wikipedia has a good article on IPv6. Of course, you need to know
IPv4 before studying IPv6.

No, learning IPv6 is easier, as you do not need to know about NAT for
global communication.
