Release notes for the latest version of the Safari Technology Preview, essentially the beta version of the macOS Web browser, explicitly state that the update ends support for Adobe Flash. This marks the end of the line for that Web technology on Macs.

The change happened in Safari Technology Preview 99 and is likely to hit the public release sometime in the near future.

Apple already disabled Flash by default in a previous Safari version, and the practice of including Flash on each Mac from initial installation ended a decade ago. But if users wanted to download Flash to their Macs and manually activate it, doing so was still possible. Soon, it won’t be—at least, not in the system’s default browser.
