I can answer this as I’m currently on a two-week holiday and I have a small homelab running at home.
First and foremost: fire alarms. Buy them, and use plenty of them.
Secondly: let your neighbors know you’re on vacation. This implies a certain amount of trust with your neighbors, but it’s good to be on good terms with them for more reasons than just this.
Thirdly: I get notifications if a server goes down or a fire alarm is triggered.
With all this in place, I don’t worry at all. I may be somewhat ignorant or oblivious to certain risks, but in general I trust the safety net I just described.
