What digital formats are compatible with Apple (pls read full description)

So I have this thumb drive that I use with my iPad and I store all sorts of stuff on it (memes, funny videos from my camera roll, etc) and I go to use it on my android phone to look at some of the memes I saved to it and it says that I need to re format the friggin thing to use it and that left me wondering if there are any formats that are compatible with Apple or if I can only use it with Apple devices now? Like can I access the files, photos, or videos on it if I were to hook it up to my chromebook, a pc, other non Apple devices, etc, you get the idea.

(Also by photos I mean screenshots)

also is there any way to see when the thumb drive was accessed on an iOS device (like timestamps and whatnot)? This is just a random question I have and i figured since this post is about thumb drives why not just ask it since it’s also related to thumb drives
