Pop OS is very bloated. If you're looking for something on the lean side, check out Manjaro.
it's a bunch of effort though, both to learn how everything works and to set up all the things you're usually just used to being there by default. but once it's done you'll be able to fix any issue that pops up, because you actually KNOW what's on your system, as opposed to it being a massive collection of things you have no idea about.
*something like gentoo might be better but... compiling a browser takes ages and i recommend having an up to date browser, so you'll spend tons of time on that.
There are 100 distros, each with pros and cons, many far lighter than Manjaro.
