Not a mod but a decent PC these days can handle vastly longer draw distances than you can set in game, but you can manually edit the config files to get. Should be instructions easily findable.

It makes it that much more beautiful.

Just a heads up - the multiplayer mod is fun for a time, but super buggy.

I know the “sequel” for subnautica is on sale for the Steam Summer Sale and it’s essentially the same game just more content.

The only mods I’ve tried is Map as well as EasyCraft, a QOL crafting mod that allows you to craft using materials from nearby storage.
