Traefik labels - what do I actually need? ELI5 please!

When I started using Traefik, I basically just copied someone else's docker-compose from a guide about setting up media services (Sonarr, Radarr etc) with Traefik, including any labels used by that person. Everything worked fine so I have pretty much just copied and pasted the same labels on every single container (yes I know it's a pretty awful idea) so that the labels on every single container look something like this.

My docker-compose files are beginning to get quite unwieldy so I'm wondering if I can clean them up a bit by removing labels that I don't necessarily need. I've looked that the docs and while I get what each label does, I don't actually understand it (if you get what I mean!) and I definitely have no idea if I need so I'm wondering if someone could have a look at my labels and give me an ELI5 explanation of what each label does?

My current traefik.yaml looks like this.

I'm not sure if that's enough info to go on but let me know what else you need to and I'll do my best to help.
