Hey, Its up to you. As for your question network manager UUIDs are a lot like "profiles", it abstracts a lot of things away. Personally I don't like it, as it overcomplicates everything (IMO), but the UUID is just an identifier for a connection, it has nothing to do with the MAC address (AFAIK).
I like to use what is rock solid, its a router, you want it to be stable and reliable. ifupdown + nftables is rock solid and is set and forget, not to mention as its config files, far easier to "audit", rather than network manager which is a complex connection of keywords using the cli. This is one of the reasons I use OpenBSD as a router, not only is there the focus on security, but also base is very simple, and I rarely need to worry about it. Also its by far easier to backup and restore router configuration when its done via a config file, your nftables config and your ifupdown network config can be easily committed to git and backed up, meanwhile this is not so easy with network manager.
