Help buying the right Apple Watch!

Hi community! I’ve never owned an Apple Watch before so hoping to get some advice on which one is good for what I use it for! I usually own Garmin but want to change to Apple Watch now!

some features I need

- sports tracking (specially surfing, paddling, running, cardio)

• listening to Spotify playlist (premium user) without needing my phone nearby (when going on runs and so on)
• durability! I’m in the ocean every day.
• i don’t really care about being able to reply to texts or so on without the phone connected, so don’t need cellular for that

the main question I had is about the cellular vs GPS, can I still listen to Spotify playlists without my phone connected on the GPS models?
