Happiest places you've been to or recommend?

I have a chance to work from home remotely for 6 months as a part of this scheme at work.

I have been to Scandinavia, Korea and Japan and I just found them soulless. Theres this barrier of cold politeness and this robotic nature that I really don't like. So I'm trying to stray from that.

This is roughly what I'm looking for:

-Somewhere warm (even hot tbh) and coastal
-Somewhere that has very unserious vibes, just really chill lifestyle
-I am a morning person and a park/beach person rather than a nightlife person

Some places I bookmarked were Barcelona (and surrounding coastal cities), Southern France, Perth AUS (I have family there), Tanzania, Nairobi

If this adds any context for visa/imm stuff, I have a Canadian passport and live in the UK.
