Both Anker and Ugreen does good GAN chargers, but Anker is bad at doing good cables (2 of 3 usbc to usbc cable failed during the first year of use). I only had 1 cable from Ugreen, and I don’t use it often, so I can’t tell if they are good yet.
Other than that I don’t have much to say about small electronics, except maybe avoid Asus Laptops. Got 3 of them during my lifetime, all got pretty big problems, ranging from bad screens to dead touchpad and motherboards. They even forgot to connect the internal audio cable during the motherboard replacement, had to sent it back a second time 😅.
You could run a WebDAV server, like Nextcloud.
On windows it supports thin sync (meaning that it keep a reference to the file instead of the whole file), on Linux not yet, as it is still in alpha (but you can just connect it as a remote disk and be done with it. That’s how I do with mines).
If you don’t want the whole Nextcloud, there are standalone cli WebDAV servers.
