If you download ADB AppControl to you computer, you can use that to disable bloatware over USB. Do this very carefully (consult guides, and make sure you know what something is before you disable it, and don't use any program that claims to "clean up" bloatware automatically). But the great thing about this app in particular is it lets you just disable things instead of fully uninstalling them, so that this way if you fuck up it's fully reversible; if your phone mysteriously starts having problems, just remember that you fucked with it and undo any recent changes to see if that fixes it.

Anyway, you might get a noticeable performance improvement out of disabling bloatware (there's probably a lot of it), and you can remove various annoyances/"features" that have their "disable" option grayed out in the phone's own settings menus.

You can also look into 3rd party launchers, like Nova launcher - some people prefer those.

Also, check the accessibility settings, in case there's something helpful in there.

Also also, there's probably a hidden "developer options" menu that may or may not be useful to you. You can look up how to activate it - it'll probably be something like going to the about phone section and tapping on the model or serial number 10 times, or something similar to that. But I haven't looked it up exactly for your phone model. With my phone, I use this mainly to manually change the audio codec when other menus don't allow it, but not for much else. Do keep in mind most of the developer options are truly intended for developers and shouldn't be tinkered with unless you know what you're doing/have a reason.

Edit: I don't know if the s23 specifically has this, but I'd check the lockscreen settings menu to see if you have the option to add quick buttons to it, if that'd be helpful to you vs the power key shortcuts.
