light linux distros?

i have an old laptop, which i upgraded to 8gb ram from 4gb a couple months ago, i ran scripts on windows to bring ram usage at idle down to around 1.8gb, but is there any linux distro that i can use instead that takes up even less memory? i want to use it as a home pc, one that anyone can use, so something user friendly would be better

tbh i am even fine with it taking 2gb ram, as long as it doesnt randomly jump to 100% cpu usage like windows, and the most gaming that's gonna happen in the laptop is probably roblox and the heaviest work its gonna do is record my brother's online classes. should i just install pop os (following LTT's latest video)? how much resources will it take?
