One that I watch that wasn’t mentioned yet is Switched to Linux. It’s good for Linux information especially when it comes to focusing on privacy and security, but just a fair warning knowing the general Lemmy community, he does like to talk about things like politics in some of his videos (especially his Weekly News Roundups) and he’s a conservative Christian, so if that is a problem for you, you may not enjoy the channel much. When he sticks to purely Linux content his information is good, though.
