when you say some services on your network are you talking about machines or softwares?
for machines yes ups makes sense for softwares writing some scripts to run on start up should be enough another alternative can be setting up wake on Lan that way you can bring all up again wherever you are
I'm not a fan of online games therefore can't suggest you an alternative but I'm sure something better exists
chatting and making video with your daughter trough discord it's the same like having any discord employee watching you (see privacy policy ) if you are confortable with that it's fine .
I'm supposing you are on lemmy to avoid reddit right ? do the same for discord.
I used boringproxy for years and I recomend you
