Interesting. I only manage one site on Siteground and since setting it up two years, I've only logged into the bash shell. So I honestly wouldn't know.
I was helping a friend with a site on Webfaction, which has their own dashboard and it is beyond confusing. Major hassle just to get a Let's Encrypt cert on there that would work with the www to non-www redirect.
My personal stuff is all on a VPS where I installed Webmin/Virtualmin. For me it's as good or better than CPanel, but I've never used Sofatlicious (you mean Softaculus?). I used a similar thing way, way back and it had a habit of installing things in ways that I didn't like, so I stopped using those installers and never tried again to see if they had gotten better. I've probably wasted a lot of time doing things manually, but I don't launch new sites very often, so it's not a pain point.
