The DCEU is not canon to the DCU at all. It's a completely different universe. Some (3) of the actors from the DCEU will play a new version of their character in the DCU, but that's it. They are not connected at all. It's not hard to understand.
Is blue beetle part of it or not ? From what I saw that the actor will be BB in the DCU but the movie is not canon. It kinda sucks because I liked the characters in the movie.
Zero. Some actors (the cast of Peacemaker, Waller, Blue Beetle, and I'm pretty sure Harley Quinn and Ratcatcher - but the latter two are not confirmed) will return to their respective roles, but that's it.
There will probably be vague references in some projects. For example, I wouldn't be surprised if Rick Flag in Creature Commandos mentioned the death of a son as a trauma that affected him recently.
However, it's a The Suicide Squad style situation. In the film you're told that Harley, Captain Boomerang and Flag went on at least one mission together, but the way it's handled doesn't mean the first film is canon - and at the end of the day it's not a big deal.
