After a long time of users asking, Valve has actually added an official Battery Charge Limit setting in the latest Steam Deck Beta update so you no longer need to use third-party tools.
Default limit when toggled on is 80%, which generally seems like a good middle ground between usability and battery life. You can also raise the limit higher if you want more battery, or lower if you want to preserve the battery life better.
What do people set it to?
On my devices where it’s available I usually set it to 80-85%.

Plugged in 24/7? I’d set it to 60%. If I have a mix of use 80%.
