I have a fedora36 system with a single static IP. I'd now like to add a /29 to it. Ideally, I'd like to create a bridge and associate all IPs with that.

I don't understand what you're trying to do.  Can you describe it more?

It used to be that I could edit the files in /etc/sysconfig/network-scripts, but I know I can't do that any longer. Now I have to use nmcli, but I was hoping someone could guide me through that process.

They are now in /etc/NetworkManager/system-connections/
You can also use nm-connection-editor which is very nice.

It appears I need to create a profile, then activate it? But I want all 6 usable addresses from the /29 and the one /32 address to be active at the same time, much like we used to do with eth0 and eth0:0, eth0:1, etc.

You can add as many addresses as you want to an interface. You don't need the :n any more.

I've done quite a bit of reading of nmcli tutorials, and none seem to discuss how to not only add a /29 (+ipv4.addresses ?) but also have it active at the same time as the /32 I already have.

That's a rather specific and strange setup to have a tutorial for.
