I dislike that it is hard to find relevant instructions on what you are looking for. That being said, there are many channels- Matrix, Discourse, Discord, Lemmy, that have a lot of smart people that are willing to help.

I'm not a programmer and I run NixOS on my personal, family, and friends' PCs. After about three months of struggling severely, I was able to get my one flake git repo to the point where I have installed it and replaced other linux distros with NixOS on these machines. I also don't often understand the warnings that are displayed when rebuilding a configuration, but have been able to solve them so far with a little guess work sometimes.

I'm setting them up with syncthing for their home directories and am looking into some easier than rsync based programs to keep them backed up. Then I can easily reinstall NixOS, git clone the flake, and have them back up and running in the event that they nuke their PC. This hasn't happened yet, unlike on other distros. Plus, I have only received complements about the systems. Someday, if Wayland gets there, I will be able to remotely access them. There probably is a way, but I haven't figured out an easy way to do so yet.

So overall more happy and satisfied, because all things tech take time and learning.

Next step is to port my Ubuntu server over to NixOS and probably use Docker to spin up webapps. Maybe even declare them the nix way.
