Where does Network Manager store settings?
When I type:
nmcli con show wlan0
One of the settings is:
802-11-wireless.band: bg
Where is this setting stored on disk?
It isn't in: /etc/sysconfig/network-scripts/ifcfg-wlan0
I've grepped everything in lib, var, etc, and usr and I haven't been able to find it.

Check the /etc/NetworkManager/system-connections/ directory. It should contain information for all saved network connections.
Edit:
The result from the command grep '802-11-wireless' `which nmcli` (which matches) implies that the formatting of the output of nmcli is done by the nmcli utility itself and not directly read from a file. Some of the data displayed on the right columns is read from somewhere though (bg in your case). You should find one of the longer ones which doesn't seem to have been formatted by the nmcli utility and grep for that.

It's a clever approach to understanding the problem, but it doesn't answer the question of where the setting is stored on the disk - or if it is.

NetworkManager supports various plugins, which can define new storage locations for configuration information. The currently enabled plugins can be found in /etc/NetworkManager/NetworkManager.conf:
[main]
plugins=ifupdown,keyfile
The generic default plugin is keyfile, which stores configurations in /etc/NetworkManager/system-connections directory, in files similar to Windows .ini files.
Other plugins may be distribution-specific:
Fedora and RedHat use
ifcfg-rh, which will both read and write/etc/sysconfig/network-scripts/ifcfg-*files.Debian and Ubuntu use
ifupdown, which is a read-only plugin: it reads/etc/network/interfacesbut does not make any changes to it. Any configuration changes you make through NetworkManager will be saved using thekeyfileplugin instead.SuSE apparently used to have
ifcfg-suse, but it seems to be deprecated.Other distributions may have their own plugins.
Having said that, the 802-11-wireless.band setting probably gets its default value from the WiFi NIC capabilities reported by the driver. It would be saved only if you wanted to explicitly restrict the NIC to only some types of WiFi networking.
If your WiFi NIC can only transmit in the 2.4 GHz band, you cannot add a or ac capabilities by just reconfiguring the software or the driver: it would require a new radio module and a new antenna tuned for the 5.0 GHz band.
