This is on me for sure that I’ve never seen anyone be faster using a CLI compared to a GUI especially for basic operations which is what most of us do 95% of the time. I know there are specific cases where a command just does it better/easier but for me that’s not the case for everyday stuff.
I was in a similar situation as you, with an existing docker solution, looking for something easier to manage. Yunohost had this hype behind it that I couldn’t resist. At first it did seem easier with the official apps, but as soon as I needed anything outside the set boundary the dream collapsed. The final nail for me was not being able to get smb working.
Good thing I had kept my docker setup safe so it was easy to revert to it. It’s more of a pain, but it’s also more versatile and capable so I have no better choice at the moment. Portainer helps a lot.
