Hi Sam,
Thanks for reaching out to us. Can you please put the CSS at Appearance > Customize > Additional CSS:
.woo-variation-swatches .variable-items-wrapper {
justify-content: center;
}
Then check whether it resolves your issue or not. Hope to hear from you soon.
Thank You
Archive / Shop swatch alignment

It seems that the alignment of swatches doesn’t work if there is more than 1 row of swatches. For one product in my shop with only 4 variations, the alignment is correct, but the product with 13 variations doesn’t align correctly (stays left-align instead of centre-align).
