To each their own, I moved from iOS to Android in 2020 and first days I started experimenting with different icon packs, but not all are perfect or of my taste, nowadays I only use the monet icons feature for Pixel Launcher, but if it wasn't for that I'd just use stock icons lol.
You can’t change icons from the system/launcher settings. Individual apps can offer icon options, but they are internal to the app.
What a scam...
