Hi,
There are 2 things which you need to consider here, products with variants and products without variants.
For products without variants, this option to make changes to these settings which you have mentioned would still be there upfront even after you save the product, refer below:
If you are not able to view it, then it seems you have products with variants. Yes, even here you can make changes to these settings later on, please follow below steps:
Open the product, then Select All the variants and then click on Bulk Edit:
Then a new page will be seen:
Here, you can click on the column button at the top and can select whatever columns you want to make the changes to.
Then you will have the columns such as below, you can make the changes as per your requirement and click on save.
Hope this helps.
