The soundtrack for Dragon’s Crown is pretty good.
Some examples:

I'd heard of Dragon's crown but never played it. This is a good lead.

You might want to check out King’s Field and King’s Field 2.

The elven ruins works the best out of these.

I sorted a bunch of video game music into playlist for RPG purposes years ago, I took a peek at my 'forest' playlist to find some you might like.

From Everquest and Guild Wars

Kelethin is good. Guild Wars music has a quality to it that kinda irks me. The same issue I have with the FF12 soundtrack in that there's so much Sound that it feels really muddy. Like it's hard to find the core melody.

DM DOKURO is a solid choice. They did music for the calamity mod and their YouTube channel has lots of music for various situations. I would be surprised if there weren't a few that you could use. I use some of his tracks for my DND campaigns I run

Ooh. never heard of em. I'll give it a look.

Neclord’s castle theme from Suikoden. You might want to look through the soundtrack of some Castlevania games. The Symphony of the Night songs Dance of Pales, Requiem for the Gods or Wood Carving Partita might be close to what you’re looking for.
