There is a misconception that fans who want the snyderverse to continue have no interest in anything else. While I'm sure there are some fans that would fit that description, I believe many people who do love Zack Snyder's contributions to the DCEU have interest in projects he has no involvement in.
Here are some movies and tv shows that I'm personally looking forward to:
Green Lanterns by Seth Grahame-Smith
New Gods by Ava Duvernay & Tom King
Naomi by Ava Duvernay
Shazam: Fury of the Gods by David F. Samsburg
Black Adam by Jaume Collet-Serra
Zatanna by Emerald Fennell
Justice League Dark by JJ Abrams
Static Shock by Michael B. Jordan and Reginald Hudlin
