Valheim's carts are the obvious way to go: limited personal inventory weight but a cart you pull (which obviously makes you slower) that can carry substantially more.

I absolutely don't like valheims approach. The devs didn't really have a concept of what to do so they just made everything more difficult and grindy and called it "immersive" or Design choice.
Yes, the game has good sides but it's really way below the hype it benefits from currently.
Graphic... Poor due to cost /optic relation.. Called design choice
Building... Simple with modules.. Made more grindy by capping the available tool/progress and binding to player to a work bench.
Survival... I like the food system. Its simple, though getting grindy if you want to keep your health up all the time to be prepared for attacks
Exploration... Extremely simple.. Called intentional by capping the next biomes to reach with these so called bosses.
Sorry for getting off topic.
I don't mind having a smaller inventory and expanding it with bags, backpack, etc
Even for really huge loads a cart, which is confirmed anyways.
