OPNsense setup – sense check (pun intended)

Hi,
I've had a fun few days setting up my Protectli VP2440 with OPNsense.
However, I'm a novice with only a little bit of knowledge so I did it all with Claude AI.

However, that means often blindly copying their instructions and now its all done and everything works I can't help but think… have I left a back door open somewhere? Is there something else I should of done?

If one of you experienced guys wouldn't mind having a look at my Services and let me know if anything essential is missing? Or if there is anything I should look into or double check – that would be great and reassuring.
TIA
