These 3 pics were taken on my Z8. This is the level possible using a camera in the wild, There is no barrier to what other people do to get their image they post on Instagram. There seems to be a growing acceptance of images based on actual photographs but edited using Nano Banana AI or similar, which produces technically perfect images that cannot be reproduced outside of AI editing.
Ignore other photographs. Concentrate on your own workflow and get what you can out of it.
Focus stacking does not work on a subject that is moving. Assume anything sitting on a leaf is moving. Focus rails in an outdoor setting are impossible to use, save yourself the frustration.
Handheld focus stacking does work but only with a great deal of practice and a good flash. OEM flashes have real trouble with this process. Get a cheap second hand Godox TT 520.
hOPE ALL THAT HELPS.
