I tried out some of these today. Umbrel, CapRover and Tipi aren't on your list yet.

They look beautiful and have some nice prebuilt installations but it gets really ugly soon as you need a custom component. I just deleted it all and switched over to portainer.

I tried installing gnome to rdp into my oracle free tier server and it wasn't remotely (hehehe) worth it. Very laggy and direct interfaces are just far superior so no to that as well. Plus it takes up precious space and resources.

I think the best option is a dashboard like dashy or homepage to keep your service interfaces together. Portainer is excellent for container management.

These weird "OS" style container platforms are really bizarre and I don't think too well thought out. They're kinda toys really. Looked really amazing but they show their limitations really quickly.
