Newbee on Figma - Lost in Features and lose ends

The Figma Universe is a feature rich universe with many possibilities and does only work with architecture mindset. So for UX Designers for example, but they are complaining a lot anyway… There are so many learning curves and concepts which do not show any usability, obvious logic or intuitive workflow, if you do not take some lessons. I tried to find a summary, video or help documentation, which are there but have lose ends… 
So the figma dschungel is good for specialised Architects, but there are thousands of alternatives meanwhile, most of them are just small AI Apps which have solutions to certain parts of a workflow, like wireframing ect… The more easy way is Canva and the Affinity Suite, which is for free now...
