Ghost Commander is a winner for me as well, because it’s also an FTP client, and is dual-pane (and because it’s FOSS, of course). Been using it for what must be at least 10 years now, across many devices, and have no complaints whatsoever.
If anyone is intrigued, here’s a link to Ghost Commander on F-Droid.
My answer is probably boring, but it works, and I had fun with my own. Just set up Wordpress. At this point, you can find templates for any site design imaginable, and there are a million plugins for it. It’s an all-around solid platform, that has mountains of documentation. Wordpress was made for blogging, can’t go wrong there, but I’ve used it for all kinds of stuff, including ecommerce. It’s simple and effective enough that I have a hard time going any other direction.
I used to host Wordpress sites on a home LAMP server; it was a fun project that didn’t cause a bunch of headaches, mainly because of the amount of available documentation. Search “wordpress self-host” and you’ll find a whole lot of information.
Good luck with whatever you decide on!
