I dont see how e.g. arch would be super hard to maintain.
There is a nice GUI program for installing programs and updates. (like many modern distros)
If you dont want to set everything up, go with Endeavour or Garuda.
I find rolling release to be easier to maintain and keep up to date than non-rolling.
Specially if you want up to date packages for desktop use.
Ionos.. not a good provider.
Great it works for you, but i wouldnt touch them with a long pole.
Created by an old internet provider (which is also not very good..), pulling every shady marketing trick weird "cloud" providers have..
Contabo is very cheap too, but i wouldnt trust them with critical stuff.
Netcup is next, quite good and still cheap.
Hetzner is very nice, but the cloud offers are expensive. the dedicated server offers though.. holy sweetness, specially the auction servers.
Dont forget smaller providers either, they can have some good stuff, but cannot really compete with the big players. (i have one for clean ip space for mail)
Over the years hosting i learned that paying slightly more is often worth it depending on the needs.
And as my requirements went up, i moved up in the tiers. If you have a need for the dedicated servers, gets cheaper for what you get (though you need to manage the hardware side then too..)
Oh and dont forget the Oracle free offers. I dont really trust Oracle, but free compute is free.. maybe dont store sensitive stuff though
