Seeing that this is turning into a comment section with answers to the question in the title of the article, instead of comments on TFA, here goes my list:
* Miniflux as an RSS reader
* Home Assistant for home automation stuff with various door/window/movement sensors, Hue management, workflows like bedtime and welcome home
* AdGuard for DNS adblocking
* An OpenVPN VPN for me to get into my home network, and another to a VPS in another country that my network gets routed over when connecting to geoblocked content ( ip sets are awesome)
* Not really self-hosted per se ( just local) and as a replacement for what some here self-host, Obsidian for note taking and wiki.
