Dude it sounds you’re over skilled for the job. You just need to read some guides and you probably know already how networking works, very basic linux commands, linux folder structures, and then the concept of docker - primarily how it maps networking & folders from your “host machine” to the “docker container”, and how it loads services using a docker compose file. Especially for nextcloud, domain dns management and dynamic dns etc would be very helpful knowledge.
Also, just a suggestion, chatgpt etc are super useful. You tell them what you want and it spits out custom instructions for your setup, and you’re able to counter question at any point. If it does make mistakes, which it will, it’s a learning opportunity for you to troubleshoot and figure out how everything works. All the best and if you have a question feel free to message me.
Pretty sure someone would have already done it. Anything with a screen and some sort of computer behind it is low hanging fruit for doom. It’s shit like running it on a calculator using potatoes that raises the bar!
