Interestingly my 2018 OE battery says 50Ah and 490A, B24, made by Yuasa.
An apparently suitable replacement Yuasa YBX7053 says 45Ah and 450A. Both EFB stop/start.
On the terminal issue, it's pretty normal for aftermarket supplied batteries to come with the smaller posts plus adapter rings to save on variants, OE manufacurer supplies will be the single size to save on loose parts on a production line and probably saves a few cents.
