No question, the A54 would be the better phone for you. It is like an S23 lite. Not a gamer and not editing videos? The A54 is more than enough. Even if you decide to game sometimes, it can handle most games ok. Not in high graphics settings, and possibly not the best framerates either, but it can play them. Also, you will get an SD card reader which the S23 does not have.
