> When shared, photos are reduced to 2048 pixels on the long edge, except panoramic photos, which can be up to 5400 pixels wide. You can share GIFs that are 100MB or smaller.

Damn, I am wrong again. Guess the only quick, integrated way is Airdrop if the other person is nearby.
I do not see a material advantage of iMessage over WhatsApp now.
Edit: it seems like the way to ensure sharing photos/video at original quality in iOS/macOS is to select the media in photos app, and then share, and then select “copy iCloud link”.
