Do you not know how old your child is?

You can just use Syncthing for syncing.

Slight correction: I think you're mixing up LMDE with Peppermint OS.

First-party stuff from your system package manager (things you install from the official repos with APT) are pretty much guaranteed to be safe. But the Snap Store (which uses snaps instead of flatpaks and is not installed by default on Debian) has unknowingly allowed and distributed malicious apps before. Flathub with flatpaks (which I think is enabled by default on Debian) hasn't had such issues to this day AFAIK, but I would still be skeptical of stuff I install from there, and just not install apps with the Unverified badge on Flathub.

In the case of flatpaks, Flathub shows what permissions an app requests and gives it a kind of arbitrary safety level on its page:
You can click on it to see more information:
You can also use Flatseal to disallow any flatpak app from having certain permissions that you think it doesn't deserve having.

Why not just power-profiles-daemon?

For Arch users: Artix with dinit is the easiest to switch to without getting a headache, as dinitctl commands are really similar to systemctl commands, package names are pretty much identical to Arch Linux, and AUR works (but you will have to find the dinit scripts for those AUR packages that have a system service).

I can't buy it from etsy tho because my country has effectively killed ordering anything from abroad :(

Not being able to relieve basic human needs at school without getting permission first (using the bathroom, eating, some of my teachers even had temper tantrums about drinking water during class).

Don't worry, those fuckers will find a way to survive through anything.
