There is this mostly French community (second language English) called yunohost (read y u no host) that provides a selfhosting solution accessible for beginners. They even offer one free domain to familiarise yourself hands on (+letsencrypt certificate). I have been using this for two years and it works well, I ran into issues but learned a lot in the process, community and devs are nice and helpful. Based on debian. https://yunohost.org/#/index_en They package most of the popular applications you’d expect for selfhosting (nextcloud, owncloud, WordPress, drupal and easily a hundred other apps)
I’ve used Yunohost for two years and a half, it is good for me to step up my Linux / cli game while enjoying a fully featured and functional solution. I played a bit with Linux at work decades ago but couldn’t have found the time back then to dig into selfhosting from scratch. It is still a good solution for me, I am also looking at Runtipi for the next setup, that I will install at a family member’s house, mostly for mutual backups. All I read however points to the fact that debian + docker is not far out of my reach. Runtipi seems like a middle step
