Just use Wormhole for file transfer. Small and easy to use. I have put on all my computers, laptops and phones.

100% of the time when I want to share a file from my phone to another phone, the other phone is not owned by me and I can’t just install some software on it

Granted, this is an edge case: I'm a musician. I use an Android tablet for sheet music. That's great when I have WiFi access, otherwise, file transfer is hard. Not impossible, but awkward when show time is in 5 minutes and someone has brought some brought some new material that they want the band to play.

The almost universal solution is "should have gotten Apple."
