Others have already supplied a bunch of very handy guides and sources, as well as the disclaimer that the possibilities for selfhosting pretty much anything are endless.

That being said, I want to supply my own source, a guide I’ve started writing up to bridge exactly this gap: https://how2host.it. It’s still in development, and I’m working on more and more detailed guides. It’s also most definitely opinionated (the use of Linux as the host, docker as the containerization and nginx as the reverse proxy, as well as a bunch of other things) but it’ll provide you with a solid foundation of knowledge which you should be able to expand from yourself.

I hope it can be of use to you!

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

Check out yunohost

Take a service you enjoy (say movie watching) and researvh something that interests you.
For example jellyfin or plex. Now you get to the question of how to implement that.
No you research that. 10-40 browser tabs later you got most of the neccessary information and implement it.

Repeat that cycle.

Now you want to pull it all together (say make it reachable from outside). You research security practices and find, that maybe you want a reverse proxy + 2FA + Fail2Ban.
Now you do it again but with the intention of not one single application but many.
When you get your stack together, you begin the next project like securing your stack, improving it etc.

Theres no FAQ on how to start it because everyone begins differently.
Some do media hosting, some want a backup solution centrally managed, some need a document management system, accounting/budgeting, security, development etc.

My personal journey was
Raspberry Pi
Linux
OpenMediaVault
Network shares for Windows
Plex
Ditch plex for Jellyfin
Find out docker exists
Dive into torrenting so *arr stack + Jellyfin automation
Get help from a discord on how to get started with traefik
Introducing Authelia
Trying random projects

If you want a hand holding (no offense. Everyone may need it at some point) guide, take a look at Ibracorp. Both the community as well as this, reddits and other communities have awesome guides on how to configure something.
But at the core of everything is one: What bothers you and how do you intend to change it?

I‘ve recently started using Tailscale for my home setup and I really can‘t recommend it enough. In my opinion it takes a lot of the dangers regarding IT security out of self hosting. Depending on who you ask it is not true self hosting, but I couldn’t care less :)

With Tailscale you can create a VPN for your devices including your phone and even expose services to the outside world with SSL already setup (havent tried that out, yet)

They have guides/tutorials for a lot of stuff (web server, Minecraft).

Additionally, is a self hosted server only accessible inside my home? What about accessing the services outside, like Bitwarden or Nextcloud apps that require syncing and availability of data wherever I am? If it is useless outside, there would be no point for me personally to self host in the first place since I am perfectly fine with using cloud services for now and the convenience that comes with it. Plus, no one else in my family cares about self hosting and I don’t wish to spend the effort to convince them to in vain, so setting up a server for convenience of everyone at home is also out of the question.

It is only accessible from your local network (if it is there in the first place, you can always selfhost on rented virtual private server), until you make it accessible. There a different ways to achieve that:

• Wireguard tunnel
• cloudflare tunnel
• (reverse) ssh tunnel
• dynDNS
• opening ports on your router

Which is the way for you depends on the circumstances, how your ISP connects you to the internet mainly

What do you have in terms of available hardware?
