I was reading into this recently too. My understanding is that Debian + LibreOffice install the Liberation Fonts by default so usually you don’t need to worry about documents using Ariel and Helvetica (Liberation are metrically compatible replacements).
After further reading I ended up also installing the Crosextra fonts, the advantage of those two is that they are metrically compatible with Microsoft’s Calibri and Cambria. Once installed in theory LibreOffice should be able to open documents that had those Microsoft fonts and auto replace them with the open versions. (there’s a setting in LibreOffice to force font replacements but it didn’t seem like I needed to do that in my case)
Some more info on that

Also interestingly - if you do really, really want some of Microsoft’s fonts they are free to install but I don’t think you actually get a license to distribute/publish with them. I didn’t bother installing these but could be useful for someone with tons of old MS Office documents with lots of random MS fonts.

Right now using a pfSense router, it’s been working well but I’ll eventually replace it with hardware to run OPNsense (pfSense fork) when the time comes.
If you’re mainly just worried about wireless I’d just look into something to run OpenWrt or maybe FreshTomato if you’re sticking to older hardware. I have an older Linksys wireless router that is compatible with FreshTomato firmware so it’s been running on that and works well for my own usage, nothing fancy.
