UPNP - Yes or No?

I've always left UPNP on, on my routers as I have smart devices, couple of games consoles, smart TV's etc.

I have read on various sites that this should be the first thing you disable?

No. Don't enable it. Most things don't need it anyway.

Disable it and see what breaks. Then decide whether you can live without what's broken.

The last piece of software I used that needed UPNP was MSN Messenger / Windows Live Messenger for file transfer. That closed years ago. Since then I have ALWAYS disabled UPNP. Some game systems MIGHT use it (e.g. Xbox) but start with it OFF.

If you factory reset a router, then always check and turn it off. (I also turn of WPS at the same time).

I recommend you disable and also check if you are forwarding any ports. If possible turn these off and use a VPN if you need to access devices such as a NAS or IP Cameras.

Couldn't agree with Sarah more on this one. Turn it off !

Trying to think of what would actually use it now a days?

You could always forward a port manually if you need to.
