Hello Michael
Yes, it does seem that those two Cessnas are the only substantiated claims by Mig-29
Another strong candidate is Armenian Su-25 shot down over Vardenis during Second Nagorno Karabah war. Armenians tried to spin this loss as shot down by Turkish F-16-s based in Azerbaijan, but it is much more likely, that it was shot down by Azeri MiG-29 (S-300 was less likely because of mountainous terrain). That Su-25 was trying to catch Azeri drones, that were attacking buses with Armenian "volunteers" moving to Karabah.
