Turn down the UI scaling. That works well enough for me. I also run Nova7 as my launcher, so I can control icon and text sizes independent of the UI scaling.
Scaling UI doesn't increase the number of buttons in the top at drop down visible at the same time. They use to be 9 before Android 10 I think. In Android 12 they are even bigger. Scaling down won't fix it. I already use it scaled BTW.
