What fediverse software should I host?

I'm looking into hosting my personal instance of some fediverse software. I want to do it to grow my tech-literacy more than to host my own service. So I want to pick one in the fediverse, because I love the federation concept, but I'm open to a software I don't use yet.

I have made previous attempt at hosting internet services a few years ago, mainly things my teachers told me to do. It was a big failure and I mostly remember from it that I got a hard time understanding instructions given on internet tutorials or at which point what I did was different from what my classmates did :( But I want to try again and do better! 😤

I plan on hosting it on a old laptop I hope not to break completely and maby in a docker container (but I also used to have a hard time with docker)

What fediverse software would you recommend me? Is there one that is easier to install than another? Or one with more clear installation instructions?

Thanks for your advice!
