Self-hosting

I have been thinking about self-hosting lately. I've built and maintained my own simple websites, I've played a bit with raspberryPi and other boards, so I have some general idea. But I have just found out that I can not use my shared hosting to host a fediverse instance (or is there anything out there? My provider offers a Softaculous install of Hubzilla but it doesn't work). So I've looked into VPS, and into self-hosting at home. I'm concerned that the learning curve for managing one's own server might be rather more than I want to have to deal with right now. Is there a good tutorial or overview for half-dummies like me, so I can better gauge if this stuff is for me?
