Sorry, but this sounds a bit: "I'd like to eat this piece of cake, but also still have it available to me when I'm done."

There are front-ends that can make docker apps easier to manage, like CasaOS. The tradeoff for ease of use is flexibility compared to something like Portainer or the CLI. CasaOS's app library (for instance) frequently has out-of-date versions of apps, and if their default configuration doesn't make sense for your purposes, you're still going to have it delve deeper (whether in the CasaOS UI or another tool) to customize things to your needs.

That's pretty much a given with any tool - if you don't want to deal with how it works, then you need to accept the default configuration and cross your fingers that it works for your purposes.

And you're still not going to get away from the fundamentals of how docker works, if you find them troublesome for some reason. Updating a docker app with something like CasaOS is doing the same thing it would be with Portainer or the command line. I'm not quite sure what seems "wrong" about it to you, but it would be "wrong" in the same way no matter what front end you use.

Personally I’ve been running docker via Unraid for about a year now and while it was easy I had very little understanding of what I was doing beyond following the instructions provided with the templates.

About a month ago my Unraid machine nuked itself and rather than rebuild it as is I decided to take the opportunity to try something new and set up Ubuntu Server on a Raspberry Pi I had lying around and set up docker on it from the ground up. Terminal only. I did install portainer but I’ve only used it for monitoring, and tbh I could probably just shut it down at this point. I learned far more in a week of getting a few containers running than I did over months of running via a web ui. I actually started with pure docker run commands and then moved on to docker compose to get a fuller appreciation of the whole process.

Honestly not knowing yaml won’t hurt you too much. Biggest thing that bites pretty much anyone going in is that yaml absolutely cares about whitespace. Keeping indentation consistent is essential. Once you get a feel for it it’s surprisingly intuitive.
