How do I amend garden beds? Perlite is ugly

I want to make my soil more aerated and draining and I don't know much about anything, lets be honest. Right now it's mostly miracle gro cactus, citrus palm mix I think?

I just hate how perlite looks with all the white dots! Its fine in my pots, but yeah.

Im looking at pumice, orchid bark, gravel, gritty sand (which is tiny tiny rocks??) etc, what do I do? I also mostly just have access to home depot and Amazon :/

And should I try to get 50/50?

Please help 🫣
