I would recommend prowlarr instead of jackett for indexer management, and pihole as at least an additional blocking service but in reality it’s really all you need for use at home. I’d also strongly encourage use of a VPN on your *arr download services. I use a separate box to run Plex and then have my *arrs all running on their own VM inside if it to provide separation and allow be to more easily segregate the network traffic (as someone that doesn’t really know docker that well it “just works” for me. Also probably worth looking at how to store your media on an external target, it’s easy to quickly accumulate 10s of TBs of media and trying to store that all on the server locally is asking for trouble. Better to set everything up on a NAS to start.
Or you can use something like Squarespace or Wix and have a fully functioning website with everything you need in a few hours and start monetizing your views with ads. Both start at $16 a month so it’s a larger hill to climb sure but you get custom branding and don’t have to deal with the baggage of a Medium page (largely that it’s considered in many circles an untrustworthy source for pretty much any topic mainly because of how easy and barrier free it is to write there. They also have a pretty well established history of working to screw over contributors to profit off of your work including you automatically giving a full license to medium for everything you post).
If all you want is a newsletter though without a webpage to back it you can setup something in mailchimp with a custom domain (.coms start at about $10 from cloudflare). Again an hour or so of reading and configuring and you’re on your way, with an Adsense account you can even embed inline ads to your newsletter.
