Glen Rice and Grant hill were mainly SFs, unless you want to add LeBron and Durant and Melo to the 2000s list.
And your 80s/90s list is two decades versus less than a decade to your Mid 2000s to current list. Not particularly equal footing you're comparing. Jordan's 2-guard contemporaries in the mid 90s during his championship run were Drexler, Reggie Miller, Penny, Craig Ehlo, John Starks, Dan Majerle, Jeff Hornacek, Vernon Maxwell. You can add the younger SGs during that time like Eddie Jones and Michael Finley.
In the 2000s, Kobe, Wade, T-Mac, Vince are a pretty strong SG group. They're all old and finished now. But that's pretty strong. And in the mid 2000s, you also had guys like Ray Allen, Rip Hamilton, Ginobili, pre-injury Brandon Roy. It's only been in the last few seasons that the SG position has gotten extremely weak.
