Number of clicks is not important. In old system upgrading buildings was chores because there was no thinking process involved. In current system, before I upgrade something I check rare resources I have, pop situations of the planet and other planets if I need to resettle, current need of my empire, what kind of world the planet is and so on. In the process I click way more than just upgrading a tile but it doesn't feel like a chore.
Also upgrading building is defenetely rewarding. It's one of the few ways to increase job in your planet. More jobs leads to more pops which leads to more buildings and merchants.
I rarely have issue with unexpected promotion because I'm playing slaver empire now but I can see how it can be problematic since you have no control over which pop promotes.
