Is Galaxy Watch the smartwatch for me?

[Android Central Question]

Hello. I have a Nokia 8.1.
I'd need a smartwatch to:
- check notifications (Whatsapp, Outlook, Gmail) and dismiss them (and get them dismissed also from the phone)
- sync gmail calendar and get reminders
- use speaker and microphone to answer to calls and to whatsapp messages
- pay using NFC
Can this watch do all these things?
I'm concerned about the compatibility, I read something weird with Nokia phones.
Thank you
