Microsoft and Google installed on Apple iPad 9th generation 15.7 (19H12)

I typically work on a PC that is running Windows (11 Ver. 22H2 OS Build 22627.160). I use both OneDrive and Google Drive for Desktop (streaming cloud storage) respectively for Microsoft 365 and Google Chrome. I have my favorites in both and have cobbled together a semi efficient working system for work/personal efforts.

I was just given an Apple iPad 9th generation 15.7 (19H12) and am new to iOS.

Any recommendations on downloading Microsoft and Google apps inside or outside of my Apple OS?

Any extensions, macros, widgets in iCloud that combine and/or manipulate Google 1 and OneDrive files?

Is iOS capable of handling my GitHub/Azure/Docker programs and interfaces?
