Cloudron.io seems pretty nice, speaking as someone who uses/works on a different platform (Sandstorm.io). Cloudron is going to cost you money if you want the benefits of automatic updates and the like, which is a downside for some (I think paying for good products/services is worthwhile), but I absolutely think making management of a ton of apps simple like a phone is the key to self-hosted online services. One of the biggest features of a good self-hosting platform should be unified authentication and identity, so you aren't managing your account on a dozen different apps.

I've always been impressed by Cloudron's well-maintained app library and constant march of major feature improvements to the platform.
