The amount of perpetuity is different. If you choose a different license for your modifications somebody could theoretically remove the base asset and replace it. In that case they wouldn't need to follow the license of the base any longer. With cc by-sa it would still be under by-sa in that case.
That rarely gets done and is probably even harder with artwork than with software, but FLOSS Open 3D Engine is a prominent example that did such a thing with software. They licensed CryEngine, modified it and built stuff around it to make it into freeware Amazon Lumberyard. Then they replaced the CryEngine stuff and released under MIT/Apache dual-license.
CC-BY-SA requires derivatives to have the same license. CC-BY doesn't, but the basis still stays CC-BY and doesn’t allow additional restrictions. CC-BY explicitly allows to put derivatives under CC-BY-SA since that would be additional restrictions otherwise. You probably can put your modifications under cc0, but that would be pointless as that wouldn't really give any additional freedoms as the base still is CC-BY. Users would need to read and follow the Attribution Notice fineprint, which is not really expected for cc0 and not what people are looking for that search for cc0 assets.
OGA's interface doesn't support assets well that have different licenses to different parts of it. It somewhat expects that everything has the same license. You can pick multiple licenses, but that is understood as dual-licensing, which means that one of the licenses can be picked and not that all apply at the same time.

Luckily there are strong precedents against companies retroactively enforcing license agreement changes.
cc0 gives you the freedom to distribute it under more restrictive terms
"Please be aware that while all Images and Videos on Pixabay are free to use for commercial and non-commercial purposes, depicted items in the Images or Videos, such as identifiable people, logos, brands, etc. may be subject to additional copyrights, property rights, privacy rights, trademarks etc. and may require the consent of a third party or the license of these rights - particularly for commercial applications."
That is generally the case, maybe not the "additional copyrights", but the rest definitely. Creative commons is based on copyright and gives you only freedoms regarding copyright.
If you use something commercially you also have to follow commercial property protections (patents, trademarks …)
The right of one's own picture is a personal right derived from human dignity. If you allow somebody to photograph you that permission is always in a certain context. You can put images into a different context via captions and modifications (especially porn captions, fake nudes and deep fakes). In the worst case that can be defamition, which is a crime in some countries.
You can neither do anything else that constitutes a crime.
Hehe, you have to take into consideration all the ways this platform can be written.

Adaptations can be 4.0, but you would still need to state that the base is 3.0 licensed.
