A lot of good information here so I’ll add something a little different:

Do Not open any services to the internet, such as for remote access, until you are sure about what you are doing. Doing something like opening a port so you can watch Jellyfin anywhere sounds great, but doing it wrong pokes a huge security hole in your infrastructure.

Keep everything in your local network until you have a secure remote access setup. Even your home network may be untrustworthy if you’ve got things like IoT devices or compromised operating systems.

Final Fantasy XI is still a beautiful game and is self hostable, but as with most MMORPGs, you need lots of people to get the full experience. Luckily if you’re hosting your own, you can always mod settings to make yourself lvl 99, turn off enemy AI, teleport anywhere, or whatever.
