Valhiem Plus should be your first stop. It has a lot of different things you can change. It will do carry weight and inventory and a lot of other stuff. You have to go into a text file to change settings, but it's pretty self-explanatory once you get in there. Backup the file and rename it before you mess with it just in case. V+ also has some settings to make building placement easier, and can speed resource collection if you're more interested in building.

I also use Vortex as a mod manager and that works pretty well. It will automatically get everything where it needs to go when downloading from Nexus.

V+ doesn't have any graphic changes in it, so just look around on Nexus. I think there are a few that improve the textures in game if you don't like the pixel look.

Personally, I also use farm grid so my plants snap to a grid when planting and I don't have to worry about putting them too close together. You still need to clear rocks and things out of the way.

I also have Dodge on Double Tap, but that one is a bit iffy since it hasn't been updated recently. I haven't found a substitute for it yet. V+ will let you map roll forward and roll backward, but it's not as convenient.
