Alright, I am ready to give a summary about my changes. The super short version is: you learn a lot; it is quite cumbersome for a Non-IT / Admin person; the result is subtle but silently rewarding. Con: I paid my hosteurope fees for almost one year in advance which is now useless.
- Webhosting changes
At first I tried to do self-hosting which worked okay but has 3 small cons:
- I have to open a port on my router.
- I have to find a DynDNS solution.
- I have no SSL out of the box.
To improve this I switched to github pages (thx to @bastibe for the suggestion) which works well and solves all the cons from above. It is still possible to use a custom domain which I find great. If you want to see it: www.ciclista.de.

Change of email service
This was the biggest one for me and selection took me a long time. I finally settled with tutamail. It has many pros that you can read about anywhere but the con is their pricing model. They call it the “family” option but in reality it is a pay per user model which is crazy for a larger family as it is 3 EUR / user / month, I hope that they will somehow enable a cheaper version as no normal person ever needs 20 GB of storage (at least not in my family). -
change of DNS registrar
Again I used the recommendation from @bastibe and use INWX. Not only do they have acceptable prices but their service is quick and friendly and everything worked as expected. Plus: their servers and offices are located in Berlin which is local for me.
Again: if you have no experience how to set up DNS entries (A, AAAA, CNAME, etc) this is a crazy and roller-coaster experience and I would recommend trying to find a provider that does this sort of service for you (I think hetzner offers something like that). But doing it by yourself and being succcessful is also kind of cool. Thanks for all that gave very helpful recommendations.
