You could try something like yunohost to get started! It’s kind of a one click deployment platform for self-hosting, ready to use with user management, reverse proxy with SSL, somewhat preconfigured services, etc.
Ideally you can also learn the tools needed like Docker, Ansible, etc, but with yunohost and a SBC (e.g. RaspberryPi), or a €5/month VPS (easier if you want to access your services publicly), you will have a ready-to-use boilerplate that you can start building on.
Learning all the individual technologies at the same time might be overwhelming at the beginning, but something like yunohost will allow you over time to learn all the stuff around the deployment itself, e.g. how domains and DNS records work, how the SSL certificates are generated, which services you would like to set up and use, the configuration needed for these services individually, etc. And at the same time you can start using a few useful services!
Then, as you start learning, you could start setting up services one-by-one manually with e.g. Docker, either at the same server or a new one.
Don’t forget to look the admin documentation for each software you’re setting up (Nextcloud etc). And look for “awesome-selfhosted”, it’s a list of more resources and software to use and deploy!
Good luck and have fun!

I agree with this. I'm running CasaOS on a Pi4. Having the initial ease of one click installs gives you a great start, then you'll start to find that you need to manage some port assignments, then you'll start learning about Docker environment variables, then you'll be managing custom installs.
Awesome-Selfhosted is a great resource. Just browse and try something interesting.
My own recent journey went like this:
Run AdGuard
Add DokuWiki, Navidrome, Mealie
Set up Cloudflare Tunnels
Add FreshRSS, Homer, SearchXNG
I also have Nextcloud on a VPS, but the fun is on the Pi.
