I’ve been going down the slef hosting rabbit hole recently.
First, Home Assistant is worth doing - you’ve not got a smart home yet but this is the easy way to get one going. So worth it. You can buy a few cheap WiFi plugs, and plug in devices like lights or stuff you don’t want on stand by and you have the start of a smart home. A smart thermostat and smart radiator valves are surprisingly easy to set up if you want to save some money and keep your home efficient - a bit more of an investment but worth it if you find you like the ease and power of WiFi plugs.
I also recommend Pihole - it’s an ad blocker for your entire network. You can run it on Docker on x86 machines - you just point your router to use it as the DNS and it then filters all requests for you. It’s really improved my experience on all my devices.
Next, Paperless NGX - scan your documents and paperless NGX will OCR read them to make them searchable and keep them in a database for you. You can use it to go paperless. Just make sure to sort our a backup.
Joplin is quite a good note taking app which you can self host to sync your devices and keep your data secure.
Syncthing is fantastic for syncing files between devices. I sync my main PC and living room theatre PC, plus in my case my Raspberry Pi as an always on broker and local backup.
I went down the route of a Raspberry Pi 5 and Installing Dietpi as the OS. Dietpi has loads of recipes in its main app that makes it easy to get going, plus if you install docker you have a huge range of stuff to try.
There is a learning curve but it’s not too steep and I’ve enjoyed it.
