There are many guides on the internet on installation of all sorts of programs under Linux. Some require installation of other programs as part of the installation process. Often the steps described in the guides involve commands starting with sudo. How can we tell which is legit and which could lead to installation of doggy programs?

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
I think the best course of action is to pull up your boot-straps, run the installation program and post any questions here if you have a problem.
If you are concerned about a specific program / app / snap then post a question here. Hopefully those familiar with it will post an answer. At the very least some helpful souls will find some links of interest and post them as comments.
Asking for a list of all "doggy" programs is subjective. What is more practical is a list of programs that don't work in certain environments which might be applicable to some and irrelevant to others.
