I would hold off until the EU issues its update for post July 1 travel.
The rules as they stand today do not focus on citizenship (other than as an absolute bar to exclusion), but rather on where one is traveling from. Thus, an Israeli national traveling from the US to Israel would quarantine in Israel for 14 days and then proceed to hie EU destination presuming that travelers from Israel are admissible. But, the fact that the individual is an Israeli national would not make the individual admissible (without intervening quarantine) in the EU, if traveling from the US recently.
