There are a lot of websites where you can find genuinely useful information, not just articles filled with fluff instead of practical advice. For my work, I don't need any complicated programs or software that I have to customize first. But I do like to set things up so I can quickly open the apps I need or customize the control panel. I used tips from https://setapp.com/how-to/customize-menu-bar-on-mac for that, so there are no unnecessary icons and only the info I really need. Setapp has a lot of articles that are useful for me, and sometimes I just google and find solutions.
