Once you agree to letting friends and family access your hosted services, you become the tech support for any problems. Whether that be your fault, user error, etc. You should absolutely limit who you give access to. In my case, only three people can and that's immediate family. No friends, no extended family. I don't wanna deal with all that mess when I deal with it at work. Don't over extend yourself by being nice.
~~Using Cloudflare is against the ToS when used for services like Jellyfin. Your account can be limited, closed, or find yourself getting a several hundred dollar bill for data usage because you've breached the terms of service. Additionally, streaming content on free accounts incurs higher latency which I've confirmed myself Argo smart routing massively reduces. https://github.com/jellyfin/jellyfin/issues/9295 - Don't abuse what's free or you may lose it.~~
Google shouldn't be indexing your domains anyway. If it's flagged your domain, it's been indexed and scanned. Alternatively, it could indicate you have a weak point somewhere on your server and you've been breached. Google's scan picked up whatever it was. Though I doubt this is the case and just a false positive. Double check your robots.txt files and disallow everything. Most index bots respect this. You can use a community sourced bot blocker. https://github.com/mitchellkrogza/nginx-ultimate-bad-bot-blocker
I've been running my own self hosted services for almost a decade. Though I have a background in IT directly doing this kind of stuff daily at work. As long as you have a strong firewall, modern TLS, relevant security headers, automatic tools like fail2ban, and have a strong grasp on permissions, you should be fine. Before I moved everything to non-root docker, it was given its own service user and SELinux policy. Using direct DNS isn't so much of a problem. You shouldn't have any issues. Feel free to reach out if you have any questions.
RE: CloudFlare TOS, Not anymore. They removed section 2.8 from their TOS, so all content can be served through CloudFlare now, as long as it doesn't use the CDN.

Thanks for the information. Although Argo still greatly reduces latency if a user cares to reduce communication time.
Can you help me to understand how to bypass the CDN while using Plex?
To bypass their CDN (referred to caching) you need to setup a Page Rule for the entire Plex domain.

I'm hoping it's just a false positive. I have everything setup to not be indexed, and I just signed up for the google search console (to submit an appeal) and the console confirmed this. I was using cloudflare to block "bots and scrapers" and that seems to have blocked Google's scraper/indexer. My best guess is they might have flagged it just for that, so I've turned it off for now.
As for security, it's an ever-evolving thing but I'm looking at ways to tighten it up. Since everything is behind Cloudflare, I also have them setting up SSL certs, and running firewalls. This lets me auto-ban "known malicious actors", as well as any IP's that aren't geo-located to the US. Server-side, it's not great though. I'm running unraid, which is... not known for it's security. Not sure if there is much I can do about that though until I re-architect everything on a proper server.
You should for sure move away from a proprietary OS. There are many ways to go about it. I personally use Arch minimal with hardened kernel. Everything runs in non-root docker containers. Commonly used distros are Ubuntu and Fedora. But there are many more to choose from. https://distrowatch.com/search.php?category=Server
Yeah, I used to run on proxmox and tried to roll-my-own stuff. I found it to be a lot of work in the areas I was less interested in, if that makes sense. I liked unraid for it's ease of use, although I think in the end the gameplan is still to eventually move docker/applications off of the unraid box and have it be only for storage. Then I can have a regular linux box for all my applications & vms.
The Google warning page isn't from a scan. I've seen it show up when visiting an entirely internal site in Chrome. It's not exposed to the Internet, and the domain name doesn't even exist in public DNS.
