Instead of the full-blown Mastodon, you should also look at #GoToSocial which is compatible and pretty light-weight. (Doesn’t come with a web UI, so you need to use client apps.)

You can create dashboards with only the useful data you need!
While dashboards are nice to look at, I very much prefer to just configure Zabbix to only notify me in case of actual problems and leave me alone the rest of the time. 😉 Also, Zabbix has capabilities to show graphs and create dashboards as well. No need for Grafana here.
At least in Germany, many of these copyright claims have no real legal grounds and wouldn't hold up in an actual trial. All cases I've read into so far ended with a settlement - as the private person was too afraid of even more legal fees. Or were dropped completely after a while (full of empty threats) if the people never engaged with the other party.
DMCA is only valid in the US. Those other countries obeying it are usually just doing it to avoid trouble, but there's no real legal obligation. (But if ignored, it is pretty safe to assume that any bigger company would look into local laws and try to find a different way.) But from what I've heard, hosters don't just close your account because of some DMCA. They will actually look into it and work with you to solve it.
And in the end, you could simply host it on a Raspberry Pi at your home. The ISP can't be held responsible for the data you transfer, so they won't just shut down your Internet connection. And if you get a strongly worded letter from some company, you can send it directly to the recycling bin.
But they can’t just DMCA it under false premises. GitHub and others just don’t want to risk anything and are pretty quick with taking down repos without checking anything.
Also there are still a few countries that don’t bow before the US-invention that is the DMCA.
So far nothing bad has happened and the company was founded so they can sell support hours to businesses. Just like lots of other companies behind Open Source projects do it. 🤷♂️
If you want to learn about VLANs and spend some time setting everything up (and more time each time a new device joins your network) then you should go for it.
I for myself decided it’s not worth it for my little home network and instead just use a /16 net and group devices into different ranges. E.g. computers are xxx.xxx.1.yyy, phones are .2.yyy, etc. All unknown devices get a .99.yyy from the DHCP, so they are easily identified.
All public facing stuff is in some Docker container, so there’s at least a small hurdle should something/someone get access.
Cameras are mirrored into Apple HomeKit via Home Assistant, so I can use Apple Home to watch them from afar. Or VPN into my home network.
Just don’t use public and free services like GitHub or GitLab. Setup your own webspace with a trusty provider, install Gitea/Forgejo and host the code yourself. It’s that easy!
Does your provider not give you access to the webserver log files?
What’s next? Do they maybe also want landlords to cancel renting agreements over this? Supermarkets to not sell to these people?
