The A54 would likely cover your needs, only you can answer if the S23+ is worth the extra money. You may also want to consider the S23 FE. A 3rd option priced between the other two.
The A54 would be a nice upgrade for my wife from her A51, but she’s all about purple, so I can see an S23 FE in her future.
We’re pretty close to Black Friday so I’ll wait and see what that brings.
Honestly there is no bad choice there. Obviously, if the budget is tight, the A54 should serve you just fine. I’d look at the Black Friday deals and choose from there.
