For 2023 my wife's side business'/hobby will generate over the $500 income threshold - can I then deduct expenses for that hobby ( income )?

[NCperson]

is this a hobby or a for-profit business - 

you can deduct expenses either way, but if it is a hobby, the loss is not deductible.

There is no $500 threshold.  All income must be reported, no matter how small it is.
