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.
