Best Wi-Fi + Bluetooth portable speaker for Spotify Connect + pool parties + great low-volume sound?

Looking for the best portable speaker that supports Wi-Fi + Spotify Connect (so music keeps playing even if my phone leaves/dies), while also being loud enough for pool parties *and* sounding great at lower volumes.

I was originally ready to buy a Sonos Move 2 or JBL Boombox 3 Wi-Fi, but then I found Speaker Ranking and got tempted by some of the insanely highly ranked/value speakers there.

The Earfun Uboom X especially looked amazing for the price, but It seems out of stock/discontinued everywhere. It’s also Bluetooth only — no Wi-Fi/Spotify Connect support

So now I’m wondering what the actual “best” speaker is for this specific use case if budget isn’t the main concern?

Thank you!
