Surely all those do have FOSS alternatives?

I have been using Vikunja instead of Google Keep. I like the mix of todo list and kanban board. I also use audiobookshelf for podcasts and audiobooks, then calibre for regular books. And a very lightweight rss app.

I’m a little more advanced with selfhosting at this point though. I use a combination of intel NUCs (RIP) locally and Digital Ocean to run Kubernetes clusters. I have a whole setup with argocd, gitea, authentik, tekton, prometheus, loki, grafana, etc, etc. But its a been a learning process that started with a rpi too.

I highly recommend mini pcs for selfhosting. Especially the intel ones since they have quick sync which is a pretty good hardware transcoder. Not sure about AMD ones, they might have something similar.

Oh, I use homepage as a homepage, but there as so many and I sometimes switch around a lot. Its good to have variety there.

If you use Let’s Encrypt, or any public CA, all of your domains and certificates will be public. You can use a wildcard to avoid revealing subdomains. There is a website that you can use to search what is available, but I don’t remember what it is.

I suspect there aren’t any serious risks to having that information revealed. The only real reason would be privacy against which services you are using on that domain.
