If ypu have the hardware but not the forwarding capability like me, you can use cloudflare tunnels for free, or setup headscale on a free orical vps. Otherwise go with the cheapest vps you can find (Im using Hetzner, but ive heard good things about netcup, or even Oricals free teir vps and move off of it if you end up not ditching selfhosting), play around, and if you need more power its as trivial as backing up your services and putting them on a more powerful server

Cars: Anything released without wifi/calling. I dont think any modern electric predates this, but you can convert diesels to friendlier oils or most engines to a run off wood. As a bonus higher trim older cars used a lot less plastic

Smartwatch: Pinetime

3D printers: id like to add Sovol, not sure about their more recent ones but their older ones either didnt have wifi or run regular klipper. The SV06/SV06 ACE are also entirelly open source except for the GUI, but you can install other klipper GUIs (theres also a repo with steps to build a minimal Debian install instead of relying on sovols firmware updates)

Routers: GL.iNET Use a modified OpenWRT install out of the box but can be flashed to vanilla OpenWRT through the GUI

Its really stange seeing kanidm basically never mentioned in these types of threads dispite how perfect it is for selfhosting: great documentation, incredibly easy to get setup, easy to make a custom themed/setup auth page, lets users name themselves how they prefer instead of requiring “firstname lastname” (why does every service need a lastname when it never gets used?)

Authelia and authentik are cool but are way more complex then you need for authenticating a couple services and for me at least feel “bloated” for my usecase

Misskey/Sharkey are Mastodon but with added or tweaked functionality, Misskey is directly forked from Mastodon iirc
