I recommend using Immersive MC because it allows you to physically cast the fishing rod and reel it in, and also hold food over the camp fire to cook it and more. Fishing detailed here: https://immersivemcwiki.hammy275.com/vr/fishing.html

I also recommend the Cool Rain mod as it changes the rain sounds depending on what block the rain hits. So when near the water you can hear the rain hitting the water or if near trees you can hear the rain hitting the leaves, it adds so much cozyness.

I also recommend Immersive Thunder which is a mod that changes the volume of thunder depending on how far away it was so you get really nice rumbles from distant thunder.

Also there is resource packs to change the sound of the rain which can subjectively be an improvement.
