There is now a "Take screenshot" button in the pulldown menus of both my A03s and A54 phones. Unfortunately it is not among the buttons that come installed by default. To get this button onto your pulldown menu:
====
On the A54:
1. Pull down the second level of pulldown menus.
2. Tap the pencil icon. This then opens up a widget that lets you choose whether you want to edit the first-level ("Top") buttons or the second-level ("Full") buttons. I chose "Full".
3. This then opens a two-section screen. On the top are your existing buttons, which you have the option of removing or dragging around. On the bottom is a palette of "Available buttons", among which you should find "Take screenshot".
4. Drag the "Take screenshot" button from the palette to wherever you want it on your two panels of "Full" buttons.
====
On the A03s:
1. Pull down the second level of pulldown menus.
2. Tap the three-dot button (the vertical ellipsis) in the upper right. This opens a dropdown menu, one of whose items is "Edit buttons".
3. You are now immediately editing the panels of your second-level menu. There's a palette on top showing the buttons that are available to add to your current buttons (shown on the bottom).
4. Drag the "Take screenshot" button from the palette to wherever you want it on your two panels of "Full" buttons.

Yup. "One UI" indeed.
I know nothing about the history of the "Take screenshot" button because I just started using Samsung phones in October 2023. I'm guessing it wasn't available previously, since I've never seen anyone but me discuss it. Even the YouTubers explaining how to take Samsung screenshots don't mention it.
I find it extremely strange that Samsung would have failed to provide this button as a high-priority item that comes installed in its pulldown menus by default. My old LG phones had "Screen Shot" in their top pulldown menus. I don't use screen shots often, but when I need one I really need one (for example to capture an image of a ticket I've bought). I've spent a lot of time trying to figure out some reasonable way of getting a screen shot other than carefully momentarily holding down the "power" and "volume down" buttons or using a swiping gesture that might cause problems in the app whose screen I am capturing.
Even stranger are Samsung's choices of buttons that ARE installed by default. For example, in place of the "Take screenshot": on first page of the deeper pull-down (on my two A54s) is the pre-installed "Screen Recorder", which takes movies of my screen activities. I cannot imagine who, other than a YouTuber making instructional videos, would use this. But there it is, right on the first page of the deep-level pulldown.
It took me ten weeks to figure out that I can edit the pulldown menus, and that hidden away among the non-installed items is "Take screenshot". It is uninstalled by default despite there being plenty of space on the second page of the deep pull-down. Who at Samsung decided that people don't need to take screen shots any more, and that people would instead want to take movies of their screen activities? It's inconceivable to me. Anyway, I finally solved my problem, and I hope it solves yours.
The button is fairly new and older models of Samsung phones don't have it depending on the version of Android and One UI. I hardly use that button and find the screen swipe with bottom of my hand much easier.
