One nice thing about PWAs in macOS Sonoma is that they can containerize any website (unlike the iOS implementation where "Add to Home Screen" only containerizes the app if it has a manifest or service worker install, otherwise it just opens the link in a browser tab). So you can put Gmail and Youtube and the other things that you actually want/need to log in for into a webapp and not be logged into Google for tracking purposes across the entire Internet in normal Safari
[edit] Also it's nice to delete all those "native" Electron apps that are just the website with more fingerprinting probes, and run their web versions instead, for added security and the benefit of sharing the OS's web engine instead of a slightly different version of Chromium in each app
[edit 2] oh and Cohost works great as a PWA on both iOS and macOS
