The Trans-Siberian Orchestra is my go-to for some of this vibe, although it can be hit or miss based on your criteria.

antipodean christmas has little of the wintry association tbh. That said, I can't immediately think of a xmas song that doesn't touch on love etc

Heavy on the pine wood forest and cold winter nights and light on the Jesus and love

Basically all Post-metal/Blackgaze/Post-Black/Depressive metal.

Ya like smooth jazz?

piano winterlude

Classic mom music. Instrumental versions of traditional tunes often with that “Wyndham hill” vibe.

E: windham hill winter sample albums are gonna be good, earlier ones have that heady sound, later ones are more reined in.

Snowy World, Say No Snow, Ice of Life, Sasha's Theme

Agalloch - A Celebration for the death of man

Agalloch - In the shadow of our pale companion

Paysage d'Hiver - Paysage d'Hiver (Full Demo)

Winter - Into Darkness

Wolves in the throne room - I Will Lay Down My Bones Among the Rocks and Roots

You are describing the watchdog soundtrack imo

This song captures how I feel looking out at a snowy winter night: https://m.youtube.com/watch?v=sbOiD7PZsQM

It's from an instrumental piano album called December by George Winston

I have one that technically isn't much about religion, and has nothing on love

It's still Christmassy though (I mean its based it's basically an instrumental cover of one)

That being said, it's "Deadly Gentlemen", an FPS soundtrack...
