I use NextCloud which syncs my photos from my iPhone to my in-home server. Then I use borgbackup to encrypt my photos/videos and send them to a cloud provider. All of it is automated and wasn't too much of a hassle to setup.
I recently got a Xtrfy M42 mouse and it requires no additional downloadable software. Everything you need to change the DPI and RGB are physical buttons. Which was one of the main reason I chose it over other comparable mice.
I recently set this up with my mom and dad too, and they have been enjoying the relief of only having to memorize one password. It is also much more secure since then their previous methods of reusing passwords.
