For me, the individual plan costs ¥1200 ($7.45 / 6,50€) per month (regardless though, they all offer the same thing worldwide such as 50GB iCloud storage, access to Apple TV, Music and Arcade) with the difference involving regional pricing for the same subscription.
Is paying $/€19.95 per month for Apple One worth the money when you factor CoL and minimum wage? Also, does Apple TV really have any good shows to watch? There are higher subscription tiers for Apple One (family or premier) but I won’t be discussing those.
Only if you’re super into the Apple ecosystem and make regular use of their services.
More people are going to be paying for Music and maybe TV; not as many will be paying for Fitness, News, etc. It’s not going to be worth it unless you’re already subbed to more than just Music, and even then probably not.

I feel like I get great value out of it. I use Music, News (mostly crosswords), iCloud storage + custom email domain, and to a lesser extent Apple TV+ and Fitness, but I love having them available.
