I don't know what that first one means. You mean the glass design?
Yeah, spotlight has been rough for years, I grant you that.
I haven't seen a single ad in my system. Where do you see them?

Not just glass. It started with Big Sur at least. It's forcing narrow and/or devoid of controls interfaces into every app, breaking decades-old system behaviours (misbehaving controls, wrong or non-functioning keyboard shortcuts, mobile-like interfaces in desktop apps etc.). It's eschewing MacOS-native development for shoddy half-assed ports of iPhone software even for first-party apps. Etc.

I've seen notifications for Apple Music, and I've seen ads in the System Settings
You're probably an iCloud services user. Try a Mac without an iCloud account - it's nagging you pretty heavily to set it up, get an iCloud+ subscription, use TV and Music and Game Center subscriptions, and so on.
