Google assistant is for smart phones, meanwhile the problem is on Windows OS. Using more general dictation programs is really not the same as using Dragon, because you can customize Dragon to your speech, accent, as well as have a database of your vocabulary (including industry specific terminology, abbreviations, non-standard names for people, companies, entities etc.). So this is not helpful.
As far as using other programs to dictate into and adding to Evernote, well that makes it very cumbersome. Way too many extra steps.
With my Plus subscription looks like I do not even qualify to open a support ticket with Evernote. That honor is a reserved for premium users only.
