*.home.arpa or custom domain as FQDN for more secure remote access?

Hi! First time pve installer here and I'm trying to setup:

OPNSense (VM), Home Assistant OS (VM), Frigate NVR (LXC) in one machine.
I want to configure a firewall/router, set up VLANS on my switch and to run a CCTV system + IoT devices.

I travel a lot so I would like to have remote access to my system. While I want to restrict internet access to frigate, I would like to access pve, OPNSense, and Home Assistant if something has to be configured remotely.

I just bought a custom domain (for testing, it was only £0.70 for 1 year)

From a security standpoint, what would be the "best" option for this?

A) Setting up a custom domain + OPNSense + Unbound + cloudflare zero trust tunnels? Letsencrypt certificates? DNS Challenge? (still researching for a route)
B) *.home.arpa + set up OPNSense + WireGuard VPN access? (still researching for a route)

FYI, Everything I mentioned above are just what I could gather from the internet therefore, I have zero experience and extremely limited knowledge. Please feel free to suggest or correct me if I'm wrong.

Thanks!
