I very often have whole days in my week, probably 2 or 3 where I don't eat any meat at all. I am definitely no vegetarian, I love pork in all it's forms. But the whole idea of having to have meat with every meal is ridiculous. Beans, falafel, cheese, tofu, etc are all tasty ways to get protein and are usually quite cheap as well.
And yeah the only non open source software I use is games. It took a couple years to get off windows, but I've been Linux as my daily driver since 2015 or 2016.
This question is useless, especially here where you're going to get a million different answers from some of the most opinionated experts on the Internet.
They are all effectively the same with very minor (and shrinking) differences. The actual biggest difference is the type of release cycle (atomic, rolling, etc) and you can find multiple of those in the same distro. Again.... It's all effectively the same.
I'm gonna recommend what works for me, but it might not work for you. I like these because (again, in my specific use case) they "just worked" with little to no problems: Fedora for a desktop/laptop and bazzite for a handheld. Again.... YMMV.
Go check distrowatch and try a few different distros until you find one you like. The more popular, the more likely you can find a community to support your questions.
